    <title language="eng">Reliability assessment of existing structures using results of nondestructive testing</title>
    <abstract language="eng">Making optimal decisions about the reliability of existing structures requires that the information used in assessment adequately represents the properties and the condition of the structures. The knowledge gap regarding a structure to be assessed can be successively filled by individually purposeful observations on site. This paper gives an overview of an approach for utilizing nondestructively gathered measurement results in reliability assessment of existing structures. An essential part of measurement-based stochastic modeling of basic variables is the calculation of measurement uncertainties, which serves to establish confidence in measurement, to ensure the comparability of unambiguously expressed measurement results, and to quantify the quality of the measured information. Regarding the current discourse on how to treat information collected on-site in the context of assessment, the authors recommend that measurement uncertainty becomes an uncertainty component mandatorily to be represented in measurement-based stochastic models. The main steps of the proposed concept are presented, and the advantages of its application are emphasized by means of a prestressed concrete bridge as case study. The bridge is assessed regarding the serviceability limit state decompression using ultrasonic and radar data measured at the structure.</abstract>

    <title language="eng">Reassessment of existing structures based on measured data - Part 2: Structural reliability analyses using NDT results</title>
    <abstract language="deu">Durch die Einbeziehung von gemessenen Daten bei der Bewertung von bestehenden Bauwerken können Unsicherheiten bei der Beurteilung des Tragverhaltens reduziert werden, ohne das normative Zuverlässigkeitsniveau einzuschränken. Informationen sind die wesentliche Grundlage für die Analyse der Zuverlässigkeit von Tragwerken. Umso wichtiger ist die Kenntnis über die Präzision und die Richtigkeit der verwendeten Informationen. Aus messtechnischer Sicht kann ein Messwert, dem keine Messunsicherheit beigeordnet wurde, als wertlos erachtet werden. Liegt ein vollständig dokumentiertes Messergebnis vor, so ist die Qualität der gemessenen Information bekannt und deren Vergleichbarkeit gewährleistet. In diesem Beitrag wird am Beispiel einer Spannbetonbrücke und zweier Grenzzustände gezeigt, wie Messergebnisse aus der zerstörungsfreien Prüfung in probabilistische Nachweise von Bestandsbauwerken einfließen können und welche Auswirkungen die Implementierung von gemessenen Daten bei der Bewertung von Bestandsbauwerken haben kann.</abstract>
    <abstract language="eng">Every decision about the reliability of a structure is associated with uncertainties. The reassessment of existing structures remains a major challenge. The decisive difference compared to the design of new structures is the possibility and necessity to collect individual information about the actual condition and properties of the structure. Such knowledge should be appreciated in the reassessment in order to reduce uncertainties and increase the validity of the results. Reliability analyses using measured data require the comparability of measurement results and the evaluation of the quality of the measured information. Both requirements can be met by adequate measurement uncertainty considerations. Besides, the destructive interventions necessary for the measurements should be kept to a minimum. This paper shows how non-destructively gathered measurement results can be incorporated into probabilistic reassessments and which effects the implementation of measured data can have when evaluating existing structures, using a prestressed concrete bridge as a case-study.</abstract>

    <title language="eng">Guideline on NDT-supported reliability assessment of existing structures - Current developments in Germany</title>
    <abstract language="eng">Information about an existing structure can be collected at certain costs to evaluate the reliability and condition as realistically as necessary. This information can be relevant or irrelevant, true or biased, precise or imprecise. The incorporation of relevant and quality-assessed measured information into reliability reassessment offers the chance to extend remaining lifetimes and support decision making about optimal actions or maintenance strategies. This paper shows recent developments in a national research project that aims to produce a guideline on the NDT-based, structure-specific modification of partial safety factors. The general methodology, results from recalculations according to the Eurocodes and metrologically solvable testing tasks relevant in the recalculation of the concrete bridges are shown and compared with the non-destructive testing methods applicable to concrete bridges. A case study is used to demonstrate that as-built drawings, in this case of the positions of tendons and shear reinforcement, can be verified using the radar method.</abstract>

    <title language="eng">Towards NDT-supported decisions on the reliability of existing bridges</title>
    <abstract language="eng">A major advantage in the reassessment of existing structures is the possibility of including measured data that describe the actual properties and the current condition of the structure to be reassessed. Currently, the incorporation of such measured information is mostly unregulated. However, the use of measurement results is vitally important, since a measured data-based improvement of the computation models level of approximation can lead at least to more meaningful results, possibly to extended remaining life times of the structure and in the best case to a saving of resources. Conversely, not appreciating well measurable and relevant information can be equated with a waste of resources. In this paper, a concept for the comparable use of non-destructively measured data as basic variables in probabilistic reliability assessments is outlined and examined using a typical prestressed concrete road bridge as a case-study. An essential requirement is the calculation of measurement uncertainties in order to evaluate the quality of the measurement results comparably. In conclusion, the example of ultrasonic and radar measurement data is used to demonstrate the effects that the incorporation of the measured information has on the reliability of the structure.</abstract>

    <title language="eng">Reliability assessment of existing bridge constructions based on results of non-destructive testing</title>
    <abstract language="eng">The non-destructive testing methods available for civil engineering (NDT-CE) enable the measurements of quantitative parameters, which realistically describe the characteristics of existing buildings. In the past, methods for quality evaluation and concepts for validation expanded into NDT-CE to improve the objectivity of measured data. Thereby, a metrological foundation was developed to collect statistically sound and structurally relevant information about the inner construction of structures without destructive interventions. More recently, the demand for recalculations of structural safety was identified. This paper summarizes a basic research study on structural analyses of bridges in combination with NDT. The aim is to use measurement data of nondestructive testing methods as stochastic quantities in static calculations. Therefore, a methodical interface between the guide to the expression of uncertainty in measurement and probabilistic approximation procedures (e.g. FORM) has been proven to be suitable. The motivation is to relate the scientific approach of the structural analysis with real information coming from existing structures and not with those found in the literature. A case study about the probabilistic bending proof of a reinforced concrete bridge with statistically verified data from ultrasonic measurements shows that the measuring results fulfil the requirements concerning precision, trueness, objectivity and reliability.</abstract>

    <title language="deu">ZfPStatik - Messergebnisse rechenbar machen</title>
    <abstract language="deu">ZfPStatik bezeichnet die Verwendung von statistisch bewerteten Messergebnissen, die mit zerstörungsfreien Prüfverfahren im Bauwesen (ZfPBau) gewonnen werden und in statischen Berechnungen zum Nachweis der Tragfähigkeit verwendet werden. Dazu ist die Ermittlung der Messunsicherheit der Versuchsdaten auf der Basis des GUM (Guide to the Expression of Uncertainty in Measurement) der erste Schritt. Der statische Nachweis erfolgt durch Grenzzustandsgleichungen, die im Bauwesen angewandt werden. Diese müssen modifiziert werden, so dass jede Messgröße als Zufallsvariable in der Grenzzustandsgleichung vorhanden ist. Der statische Nachweis erfolgt mit probabilistischen Berechnungsmethoden aus der Zuverlässigkeitstheorie. Diese Vorgehensweise wird exemplarisch für den Standsicherheitsnachweis eines Plattenbalkenquerschnitts einer Stahlbetonbrücke auf Biegung angewandt. Auf die möglichen Schlussfolgerungen aus den probabilistischen Berechnungen wird abschließend kurz eingegangen.</abstract>

    <title language="eng">On the Treatment of Measurement Uncertainty in Stochastic Modeling of Basic Variables</title>
    <abstract language="eng">The acquisition and appropriate processing of relevant information about the considered system remains a major challenge in assessment of existing structures. Both the values and the validity of computed results such as failure probabilities essentially depend on the quantity and quality of the incorporated knowledge. One source of information are onsite measurements of structural or material characteristics to be modeled as basic variables in reliability assessment. The explicit use of (quantitative) measurement results in assessment requires the quantification of the quality of the measured information, i.e., the uncertainty associated with the information acquisition and processing. This uncertainty can be referred to as measurement uncertainty. Another crucial aspect is to ensure the comparability of the measurement results.This contribution attempts to outline the necessity and the advantages of measurement uncertainty calculations in modeling of measurement data-based random variables to be included in reliability assessment. It is shown, how measured data representing time-invariant characteristics, in this case non-destructively measured inner geometrical dimensions, can be transferred into measurement results that are both comparable and quality-evaluated. The calculations are based on the rules provided in the guide to the expression of uncertainty in measurement (GUM). The GUM-framework is internationally accepted in metrology and can serve as starting point for the appropriate processing of measured data to be used in assessment. In conclusion, the effects of incorporating the non-destructively measured data into reliability analysis are presented using a prestressed concrete bridge as case-study.</abstract>

    <title language="eng">Approach to the development of a model to quantify the quality of tendon localization in concrete using ultrasound</title>
    <abstract language="eng">Each engineering decision is based on a number of more or less accurate information. In assessment of existing structures, additional relevant information collected with on-site inspections facilitate better decisions. However, observed data basically represents the physical characteristic of interest with an uncertainty. This uncertainty is a measure of the inspection quality and can be quantified by expressing the measurement uncertainty. The internationally accepted rules for calculating measurement uncertainty are well established and can be applied straightforwardly in many practical cases. Nevertheless, the calculations require the occasionally time-consuming development of an individually suitable measurement model. This contribution attempts to emphasize proposals for modelling the non-destructive depth measurement of tendons in concrete using the ultrasonic echo technique. The proposed model can serve as guideline for the determination of the quality of the measured information in future comparable inspection scenarios.</abstract>

    <title language="eng">Methods to Quantify the Utility of NDT in Bridge Reassessment</title>
    <abstract language="eng">The purpose of this contribution is to introduce and to apply the developed approach of incorporating non-destructively gathered measurement results (instead of deterministic information and assumptions) into a reassessment model of a typical prestressed concrete road bridge and to outline the advantages. An essential part is the quality evaluation of the non-destructively measured information, that deals primarily with two questions. Could the object or parameter to be obtained reliably detected and if, how accurate are the inspection results achieved? Therefore, the importance of the combination of a probability of detection (POD)-approach and measurement uncertainty calculations is emphasized. With regard to the introduced case-study it is shown, for which structure parameters an assumption deviating from the actual (and measurable) situation has a particularly strong (and possibly arithmetically unfavorable) influence on the structural reliability. Measurements on such parameters are particularly beneficial for a reliable and robust reassessment. In conclusion, the individual reassessment results without consideration and with consideration of evaluated non-destructive inspection results are compared.</abstract>

    <title language="deu">Verwendung von Messergebnissen zerstörungsfreier Prüfverfahren im Bauwesen in statischen Nachweisen - Statistisch abgesicherte Messgrößen beschreiben dem Prüfingenieur die tatsächlich ausgeführte Konstruktion</title>
    <abstract language="deu">Zerstörungsfreie Prüfverfahren (ZfPBau-Verfahren) sind auch im Bauwesen stets an praxisrelevante Prüfaufgaben gekoppelt. Die Ermittlung beispielsweise eines Ist-Zustandes im Vorfeld einer Betoninstandsetzung oder die Ermittlung von Schadensursache und Schadensumfang als Folge wiederkehrender Untersuchungen von Brücken nach DIN 1076 sind etablierte Anwendungsgebiete der ZfPBau. Mit der Einführung der Nachrechnungsrichtlinie für Straßenbrücken im Jahr 2011 hat die Nachfrage nach ZfPBau-Dienstleistungen einerseits stark zugenommen, andererseits eröffnet sie Möglichkeiten, in statischen Nachweisen die tatsächlichen Eigenschaften bestehender Konstruktionen rechnerisch anzusetzen. Dazu aber müssen Messergebnisse statistisch bewertet werden können. Dies geschieht durch eine einheitliche Ermittlung der Messunsicherheit, mit der die Voraussetzungen geschaffen werden, um Messergebnisse von ZfPBau-Verfahren in statischen Berechnungen verwenden zu können. Im folgenden Beitrag wird gezeigt, wie Messgrößen der ZfPBau als (stochastische) Basisvariablen in probabilistische Nachweise zur Berechnung der Zuverlässigkeit einfließen können, indem Grenzzustandsgleichungen modifiziert werden. Mit dieser Vorgehensweise sind weitere Schlussfolgerungen aus den Ergebnissen möglich.</abstract>

    <title language="eng">Structural safety referring to ultrasound on concrete bridges</title>
    <abstract language="eng">Measuring means knowing. The structural engineer’s Knowledge about structures is vitally important for the assessment of their structural safety. This contribution shows, how non-destructive testing methods can be used to collect valuable Information about existing structures. This value is expressed in this paper by the usability in probabilistic assessments and thus by the reliability of the information. The development of non-destructive testing methods in civil-engineering allows the realistic measurement and visualization of inner constructions of concrete components with a minimum of destructive interventions.&#13;
The evaluation of the quality of measurement data is of fundamental importance for quantitative measurements in order to ensure the objectivity of testing and evaluation and to assess the reliability of the knowledge acquired. Both systematic and random deviations must be identified, quantified and taken into account to obtain statistically sound data. The Focus of this contribution is on the methodical path, how displayed measurement data can be processed into reliable knowledge.&#13;
It is not about developing assessment methods but about providing&#13;
necessary knowledge to increase their operational usability.</abstract>

    <title language="eng">From Uncertainty in Measurement to Certainty in Bridge Reassessment</title>
    <abstract language="eng">"The reassessment of bridges continues to take great importance both nationally and internationally. A major challenge is to find computation models reflecting the actual properties of the considered structures sufficiently accurate. Besides regular inspections, the conduction of advanced measurements is suitable to generate reliable information about a structure to be assessed. Prior to incorporating measurement results in reassessment, the relevance, the trueness, and the precision of the measured information needs to be stated. On the one hand, the use of information whose quality has not been assessed can lead to errors with serious consequences. On the other, the measurement of irrelevant information is inefficient. Although the use of measured data in assessment is currently mostly unregulated, their appreciation in reliability analyses is beneficial since the built environment can be assessed more realistically. Utilizing NDT in reassessment has the potential to extend remaining lifetimes of a structure, save resources, and improve infrastructural availabilities. The power of judgment regarding the decision on the reliability of an existing structure can be increased.     &#13;
&#13;
In this contribution, an approach is outlined to process non-destructively gathered measurement data in a comparableway in order to include themeasured information in probabilistic reliability assessments of existing structures. An essential part is the calculation of measurement uncertainties. The effect of incorporating evaluated NDT-results is demonstrated by means of a prestressed concrete bridge and GPR measurements conducted on this bridge as a case-study. The bridge is assessed regarding SLS Decompression using the NDT-results."</abstract>

    <title language="eng">Non-destructive testing in civil engineering: A valuable source of information for reliability assessments</title>
    <abstract language="eng">The reassessment of bridges is becoming increasingly important. The basic requirement for analyses of structural safety is reliable knowledge about individual structures. This paper introduces the new approach to evaluate the quality of measured data gained from non-destructive testing (NDT) to provide reliable, objective, and relevant information about existing bridges. The purpose is to relate this validated knowledge to probabilistic analyses. Bridging the gap between NDT and numerical reassessments indicates reduced numerical uncertainties and residual service time extensions. This paper deals with an application of this approach using measurement data collected by ultrasonic technique at a prestressed concrete bridge.</abstract>

    <title language="deu">Bewertung von Bestandsbauwerken mit gemessenen Daten. Teil 1: Konzept, Messungen und Leistungsfähigkeit der ZfP‐Verfahren</title>
    <abstract language="deu">Gegenüber dem Neubauentwurf können bei der Bewertung von bestehender Bausubstanz Sicherheitsreserven genutzt werden, da Unsicherheiten, die beim Bau auftreten können, besser bekannt oder nicht mehr vorhanden sind. Können solche Unsicherheiten genauer bewertet werden, z. B. durch die Feststellung der genauen Lage der Spannglieder bei einer Spannbetonbrücke, so können Sicherheitsbeiwerte reduziert werden, ohne dass es dabei zu Auswirkungen auf das normativ festgelegte Zuverlässigkeitsniveau kommt. Mittlerweile sind Prüfmethoden an Bauwerken wirtschaftlich einsetzbar und auch so leistungsfähig, dass die für die Tragfähigkeit und Gebrauchstauglichkeit wesentlichen Parameter identifiziert werden können. Ein wesentlicher Punkt ist hierbei die Integration derartiger Messergebnisse in Rechenmodelle, die für die Nachrechnung des Bauwerks verwendet werden. Dies können sowohl semiprobabilistische Rechenmodelle als auch vollprobabilistische Modelle sein. Bei semiprobabilistischen Methoden können aus den Messergebnissen Teilsicherheitsbeiwerte berechnet und abgeleitet werden, die dann in den bekannten Nachweisformaten gemäß den Eurocodes und der Nachrechnungsrichtlinie berücksichtigt werden. Bei vollprobabilistischen Nachweisen können die Messdaten in Form von Verteilungsdichtefunktionen mit gemessenen Variationskoeffizienten direkt in das Rechenmodell eingehen. In einer dreiteiligen Aufsatzreihe werden die Messverfahren und die Nutzung der Ergebnisse bei der Nachrechnung vorgestellt. Der vorliegende Teil 1 zeigt die Möglichkeiten des Einsatzes von zerstörungsfreien Prüfverfahren und bewertet deren Leistungsfähigkeit. Messen heißt wissen. Dieses Wissen spiegelt die Realität wider und soll den Tragwerksplaner bei der Entscheidungsfindung über die Sicherheit und Zuverlässigkeit von Bestandsbauwerken unterstützen.</abstract>

    <title language="eng">Test specimen concepts in regard to quality assurance and validation of nondestructive testing in civil engineering</title>
    <abstract language="eng">The process of ensuring reliability of NDT applications contains various aspects, such as determining the performance and probability of success, the uncertainty in measurement, the provision of clear and functional procedures and ensuring the correct application accordingly. Test specimens have become powerful elements in supporting many of these aspects. Within the committee for NDT in Civil Engineering (NDT-CE) of the German Society for Nondestructive Testing (DGZfP), the subcommittee on Quality Assurance (UA-QS) therefore addresses the design and the integration of test specimens in the quality assurance process. Depending on the specific purpose, the requirements on test specimens can vary significantly based on the defined simulated scenario. The most prominent purposes of test specimens might be seen in providing references for inspection systems in regard to function control, calibration and validation. Further aspects can be parametric studies, basic investigation of physical principles related to NDT or a simplified and therefore comprehensive demonstration of inspection concepts (e.g. for teaching purposes). The specific purpose of a test specimen dictates the requirements regarding its conception, including the exact design, the material or the fabrication accuracy and the conditioning. In the development of a general guideline by the UA-QS for application-specific procedures and their validation, the use of test specimens is addressed and specific concepts for the design of test specimens are made. This includes the analysis of the measurement process regarding any given application, deriving an adequate calibration approach for it and designing test specimens (calibration specimens) accordingly. Furthermore, it includes the validation of the procedure taking into account all conditions related to the specific application in the field. The validation requires a statistically sufficient number of trials. Thorough evaluation of each trial can only be established if the ground-truth is known. Therefore, test specimens providing a realistic but controlled simulation of the inspection problem are valuable and indispensable elements in the validation process. The requirement of being fully realistic will often not be possible to fulfill due to practical restrictions. Any aspect that cannot be included in the simulation realistically needs to be simulated conservatively. This again, requires a sufficient understanding of the inspection principle and technique to ensure conservativeness. Among other quality-assurance-related aspects, the UA-QS establishes concepts and guidelines regarding sound and efficient approaches for the specific purposes of test specimens. This subcommittee brings together representatives of different Groups along the entire value chain of NDT-CE, including researchers, practitioners, manufacturers and clients. They all work together in establishing a common understanding and level of quality assurance in the industry.</abstract>

    <title language="eng">NDT procedures in relation to quality assurance and validation of nondestructive testing in civil engineering</title>
    <abstract language="eng">The field of non-destructive testing of civil structures (NDT-CE) has been continuously growing. Due to the complexity and diversity of civil constructions as well as the heterogeneity of concrete, specific standards or guidelines for the application of modern NDT-CE are still missing. The development of individual solutions is the current approach, which is just as challenging as it is common for NDT-CE.&#13;
With the increasing development and commercialization of NDT-CE technology, the group of practitioners is growing. To ensure a good level of quality in the industry, it appears necessary to establish adequate means.&#13;
Naturally, the performance of NDT-CE methods regarding a specific application is strongly dependent on choosing the most suitable inspection technique and applying it correctly, generally referred to as the inspection procedure in the field of NDT. There are well-defined guidelines regarding procedure documentation and handling in many fields of NDT (e.g. nuclear, aerospace or automotive) according to the high importance of procedures in assuring a successful and reliable application. For a long time, this has not always been the case with NDT-CE, which is still considered a unique discipline of NDT. Part of the reason for that might be the young development state of NDTCE, the heterogeneity of building materials like concrete, timber or masonry as a material and the diversity of civil structures. In consequence, NDT-CE procedure development is considered challenging.&#13;
Among other aspects, addressed in the subcommittee on Quality Assurance (UA-QS) within the committee for NDT-CE of the German Society for Nondestructive Testing (DGZfP), part of its work aims at establishing an adequate basis for NDT-CE procedure development. While some of the highly developed approaches from other industries are taken into consideration, they need to be analyzed regarding their suitability for NDT-CE and adapted accordingly. For a procedure to be as defined as possible, it needs to contain sufficient information, such as the scope and limitations regarding material, geometry and condition of the test object, inspection parameters, calibration, data acquisition, analysis criteria as well as requirements regarding the inspection personnel.&#13;
For a successful implementation in the field, it is important to define the specific procedure as precisely as possible. Despite the necessity of a great amount of information to be included, the procedure needs to be suitable for efficient field application.&#13;
The UA-QS is developing a guideline for NDT-CE procedures suitable for application in this field of NDT to ensure correct and reproducible application. To demonstrate and evaluate this concept, specific examples of procedures are also produced. In particular, the UA-QS has developed a procedure for the detection and positioning of tendon ducts using Ground Penetrating Radar (GPR). This procedure is tested regarding the practical applicability in a roundrobin on a defined type of reference test block.</abstract>

    <title language="deu">Probabilistischer Nachweis einer Spannbetonbrücke – Teil 1</title>
    <abstract language="deu">AbstractDer Erhalt der bestehenden Verkehrsinfrastruktur ist eine große Herausforderung, da die Bauwerke fortwährend altern, die Verkehrsbeanspruchung zunehmend steigt und deren umfassender Ersatz mit Blick auf begrenzte Budgets und Ressourcen nicht möglich ist. An Bestandsbauten können tatsächliche Materialkennwerte, Geometrien oder Einwirkungen objektspezifisch erfasst werden. Die Nachrechnung von Bestandsbrücken erfolgt in Deutschland gemäß Nachrechnungsrichtlinie nach Stufen 1 und 2 mit dem semiprobabilistischen Teilsicherheitskonzept. Nur im Ausnahmefall wird eine messbasierte Bewertung oder eine wissenschaftliche Betrachtung gemäß Stufen 3 und 4 durchgeführt. Die Einbeziehung zusätzlicher Informationen aus der Zustandserfassung bietet jedoch viele Vorteile für eine realitätsnahe Bewertung. In probabilistischen Berechnungsmethoden können solche Kenntnisse direkt in der Berechnung berücksichtigt werden. Ziel dieses zweiteiligen Beitrags ist die Vorstellung der Potenziale und Vorteile bei der direkten Berücksichtigung der Ergebnisse von zerstörungsfreien Prüfverfahren bei der Zustandsbewertung von Brückenbauwerken. Das Konzept wird an einer Spannbetonbrücke vorgestellt. Der erste Teil befasst sich mit den Möglichkeiten zur Überführung der Eingangswerte der üblichen semiprobabilistischen Berechnung in stochastische Modelle. Ausgehend von der semiprobabilistischen Nachrechnung nach derzeitigem Regelwerk wird die probabilistische Modellierung aller relevanten Basisvariablen für die Grenzzustände der Tragfähigkeit Biegung, Querkraft und Torsion ausgeführt.</abstract>

An Bestandsbauten k\u00f6nnen tats\u00e4chliche Materialkennwerte, Geometrien oder Einwirkungen objektspezifisch erfasst werden. Die Nachrechnung von Bestandsbr\u00fccken erfolgt in Deutschland gem\u00e4\u00df Nachrechnungsrichtlinie nach Stufen 1 und 2 mit dem semiprobabilistischen Teilsicherheitskonzept. Nur im Ausnahmefall wird eine messbasierte Bewertung oder eine wissenschaftliche Betrachtung gem\u00e4\u00df Stufen 3 und 4 durchgef\u00fchrt. Die Einbeziehung zus\u00e4tzlicher Informationen aus der Zustandserfassung bietet jedoch viele Vorteile f\u00fcr eine realit\u00e4tsnahe Bewertung. In probabilistischen Berechnungsmethoden k\u00f6nnen solche Kenntnisse direkt in der Berechnung ber\u00fccksichtigt werden. Ziel dieses zweiteiligen Beitrags ist die Vorstellung der Potenziale und Vorteile bei der direkten Ber\u00fccksichtigung der Ergebnisse von zerst\u00f6rungsfreien Pr\u00fcfverfahren bei der Zustandsbewertung von Br\u00fcckenbauwerken. Das Konzept wird an einer Spannbetonbr\u00fccke vorgestellt. Der erste Teil befasst sich mit den M\u00f6glichkeiten zur \u00dcberf\u00fchrung der Eingangswerte der \u00fcblichen semiprobabilistischen Berechnung in stochastische Modelle. Ausgehend von der semiprobabilistischen Nachrechnung nach derzeitigem Regelwerk wird die probabilistische Modellierung aller relevanten Basisvariablen f\u00fcr die Grenzzust\u00e4nde der Tragf\u00e4higkeit Biegung, Querkraft und Torsion ausgef\u00fchrt.&lt;\/jats:p&gt;","DOI":"10.1002\/best.202400018","type":"journal-article","created":{"date-parts":[[2024,6,26]],"date-time":"2024-06-26T12:24:13Z","timestamp":1719404653000},"page":"509-523","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Probabilistischer Nachweis einer Spannbetonbr\u00fccke \u2013 Teil 1"],"prefix":"10.1002","volume":"119","author":[{"given":"Caner","family":"\u00d6zl\u00fc","sequence":"first","affiliation":[{"name":"Hochschule f\u00fcr Technik und Wirtschaft Berlin  Wilhelminenhofstra\u00dfe 75A 12459 Berlin"}]},{"ORCID":"http:\/\/orcid.org\/0000-0003-2603-0032","authenticated-orcid":false,"given":"Stefan","family":"K\u00fcttenbaum","sequence":"additional","affiliation":[{"name":"Bundesanstalt f\u00fcr Materialforschung und -pr\u00fcfung  Unter den Eichen 87 12205 Berlin"}]},{"given":"Christian","family":"Kainz","sequence":"additional","affiliation":[{"name":"Universit\u00e4t der Bundeswehr M\u00fcnchen Institut f\u00fcr Konstruktiven Ingenieurbau  Werner-Heisenberg-Weg 39 85577 Neubiberg"}]},{"ORCID":"http:\/\/orcid.org\/0000-0003-2983-6832","authenticated-orcid":false,"given":"Thomas","family":"Braml","sequence":"additional","affiliation":[{"name":"Universit\u00e4t der Bundeswehr M\u00fcnchen Institut f\u00fcr Konstruktiven Ingenieurbau  Werner-Heisenberg-Weg 39 85577 Neubiberg"}]},{"given":"Alexander","family":"Taffe","sequence":"additional","affiliation":[{"name":"Hochschule f\u00fcr Technik und Wirtschaft Berlin Institut f\u00fcr Konstruktiven Ingenieurbau  Wilhelminenhofstra\u00dfe 75A 12459 Berlin"}]}],"member":"311","published-online":{"date-parts":[[2024,6,26]]},"reference":[{"key":"e_1_2_7_1_1","unstructured":"Bundesanstalt f\u00fcr Stra\u00dfenwesen [Hrsg.] (2011)Richtlinie zur Nachrechnung von Stra\u00dfenbr\u00fccken im Bestand (Nachrechnungsrichtlinie)."},{"key":"e_1_2_7_2_1","unstructured":"Bundesanstalt f\u00fcr Stra\u00dfenwesen [Hrsg.] (2015)Richtlinie zur Nachrechnung von Stra\u00dfenbr\u00fccken im Bestand \u2013 1.\u2005Erg\u00e4nzung."},{"key":"e_1_2_7_3_1","doi-asserted-by":"crossref","unstructured":"K\u00fcttenbaum S. et\u2005al.

    <title language="deu">Probabilistischer Nachweis einer Spannbetonbrücke – Teil 2</title>
    <abstract language="deu">AbstractIm zweiten Teil dieses Beitrags werden die Grenzzustandsfunktionen für die Nachweise im Grenzzustand der Tragfähigkeit für Biegung mit Normalkraft, Querkraft mit Querkraftbewehrung und Torsion vorgestellt. Die Eingangsgrößen der mechanischen Widerstandsmodelle werden durch zahlreiche Abbildungen illustriert. Auf Grundlage der probabilistischen Modelle aus dem ersten Teil dieses Aufsatzes und der mechanischen Modelle aus diesem zweiten Teil werden die probabilistischen Nachweise geführt. Die Ergebnisse aus der Zuverlässigkeitsanalyse werden mit den semiprobabilistischen Berechnungsergebnissen verglichen. Mittels Parameterstudien wird gezeigt, welche Eingangsgrößen im Standsicherheitsnachweis die größten Einflüsse auf die Bauwerkszuverlässigkeit haben. Die Messung dieser Parameter ist entsprechend besonders nützlich. Auf dieser Basis wird abschließend gezeigt, welche Chancen sich aus der Durchführung von zerstörungsfreien Bauwerksprüfungen für die Nachrechnung ergeben.</abstract>

Die Eingangsgr\u00f6\u00dfen der mechanischen Widerstandsmodelle werden durch zahlreiche Abbildungen illustriert. Auf Grundlage der probabilistischen Modelle aus dem ersten Teil dieses Aufsatzes und der mechanischen Modelle aus diesem zweiten Teil werden die probabilistischen Nachweise gef\u00fchrt. Die Ergebnisse aus der Zuverl\u00e4ssigkeitsanalyse werden mit den semiprobabilistischen Berechnungsergebnissen verglichen.

    <title language="eng">Guidance on inspection-supported reliability assessment of existing bridges in Germany</title>
    <abstract language="eng">This contribution is intended to disseminate the contents of a national recommendation for Action draft for the inspection-based reliability analysis of existing bridges. The focus is on the utilization of non-destructive testing methods for verifications in both the ultimate and the serviceability Limit states. First, the contents of the developed recommendation for action are outlined. The Guideline covers the process from the purposeful definition of inspection strategies via the quality assessment of measured information to the partial factor-based assessment under consideration of qualityevaluated on-site inspection results. Secondly, the concept of the drafted recommendation for action is demonstrated using a prestressed concrete bridge as a case study.</abstract>
