T1 - Strategies for high risk reduction and management as global responsibility T2 - Emergency policy N2 - In the last decades it has been necessary to face emergencies due to big crisis events caused by anthropic and natural events. In particular modern technological Systems have reached such a high level of complexity that even a simple event can influence correct behavior with potential catastrophic consequences. The security and economy of technologically developed countries depends on the correct behavior of this infrastructure and on the continuity of the Services that they grant. In this framework, risk management assumes an important role focusing on policies for vulnerability reduction and after-crisis management. It imposes a multidisciplinary and transnational approach in Order to establish a common strategy between different countries, studying how to be prepared for disasters and prevent disaster damage. In this paper a preliminary analysis of risk categories is presented, suggesting a number of tentative proposals for risk reduction.

T1 - Charakterisierung von Lehmmauerwerk unter statischer Druck- und Schubbeanspruchung T2 - Mauerwerk-Kalender 2013 N2 - Schätzungen zufolge leben und arbeiten zurzeit 30 bis 40 % der Weltbevölkerung in Gebäuden aus Lehm. Darunter befindet sich auch eine nicht unerhebliche Anzahl an Baudenkmälern, davon viele in einem gefährdeten Zustand. Bauwerke aus Lehm erfordern einen hohen Unterhaltungsaufwand, da sie anfällig sind für Erosion bei Regen sowie Abplatzungen und Querschnittsschwächung, wenn Salze kapillar transportiert werden und auskristallisieren. Außerdem sind sie empfindlich gegenüber mechanischen Beanspruchungen. So führen bereits relativ niedrige Zug- oder Druckspannungen zu Schädigungen durch Rissbildung. Einige Lehmbauweisen werden heute nicht mehr ausgeführt und das Wissen über sie ist zumindest teilweise verloren gegangen. Die verschiedenen Lehmbauweisen unterscheiden sich deutlich in Bezug auf die Zusammensetzung des Materials und die Bautechniken.

A comparison between different typologies T2 - 2nd WTA - Internaitonal PhD Symposium - Building materials and buidling technology to preserve the built heritage N2 - Traditional construction techniques utilizing earthen materials are often seen as inferior compared to modern ways of building. Structural earthen elements are perceived as vulnerable towards environmental influences (moisture, frost) and in particular towards the load scenarios during earthquakes. In comparison to the recent advances in research on stone and brick masonry, knowledge on the structural performance of earthen building construction is limited and scattered. Consequently the confidence in the performance of these earthen buildings constructed in the traditional techniques during earthquakes is fairly low. The research presented here aims to make a comparison of mechanical behavior between different earth masonry material typologies, consisting of earth block masonry, rammed earth and cob.

It aims to develop and validate innovative materials and technologies for the systemic improvement of the seismic behavior of Cultural Heritage assets. The death tolls brought about by recent catastrophes in developing countries where many inhabitants lived in earthen dwellings (Gujarat, India 2001, Bam, Iran 2003 and Concepción, Chile 2010 Earthquakes, Tamil Nadu 2004 Tsunami) have brought about research studies aimed at improving earth construction in terms of strength, seismic resistance and speed of construction. In comparison to the recent advances in research on stone and brick masonry, knowledge on the material properties and failure mechanisms of earthen Building construction is limited and scattered. The research presented here by aims making a comparison of mechanical behaviour between different earth masonry material typologies, consisting of earth block masonry, rammed earth and cob.

These monuments in the Campania region were monitored by means of full-scale environmental vibration testing. Measured responses were then used for modal identification. The procedure is based on a typical finite element model updating technique based on vibration test results. Parameters optimization is carried out by minimizing a weighted error criterion relative to the building’s modal properties. A satisfactory improvement on modal parameters is thus obtained, resulting in a close Agreement between the modal properties observed in dynamic tests and those calculated from numerical model. Seismic assessment is carried out with nonlinear static analysis of the tower under multimodal distributions of lateral loads. Nonlinear analysis indicates the potential collapse mechanisms and evidences dangerous structural weakness which may play a role in the seismic vulnerability of the towers.

T1 - Torsional seismic response of an asymmetric-plan hospital buidling T2 - 14th Conference of seismic engineering ANIDIS N2 - The inelastic torsional response of an asymmetric-plan hospital building is studied. The response of the structure in the time domain as recorded by highly sensitive sensor network, integrated by a data acquisition system. The identification was performed using techniques of modal extraction in the frequency domain (frequency Domain decomposition). A calibration process was applied in order to identify a reliable structural model to be used for the seismic vulnerability assessment of the hospital building. In particular, a nonlinear static procedure accounting for mass distribution, higher modes contribution and mode-shapes correlation was proposed for the estimation of the seismic response of irregular buildings. Finally, the influence of lateral force distribution, node control during pushover and accidental eccentricity is investigated.

T1 - Charakterisierung und Modellierung der mechanischen Eigenschaften von Lehmsteinmauerwerk / Mechanical characterization and modelling of earth block masonry JF - Das Mauerwerk N2 - Das Wissen über die Materialeigenschaften und die Versagensmechanismen bei Lehmbaustoffen ist begrenzt und lückenhaft. Im Rahmen des EU-Projekts NIKER (www.niker.eu) wurden deshalb die mechanischen Eigenschaften von Bauteilen aus Lehm unter statischer Druck- und Schubbeanspruchung bestimmt. Ziel der Untersuchungen war es, grundlegende Daten zum Verformungs- und Versagensverhalten von Lehmbauteilen zu erhalten und dieses mit einem numerischen Modell zu beschreiben. Die Versuchsergebnisse belegten das spröde Verhalten von Lehmsteinmauerwerk bei uniaxialer Druckbelastung und zeigten, dass das Versagen von Lehmsteinmauerwerk infolge Schubbelastung nach Erstrissbildung in Mörtelfugen und Lehmsteinen durch Gleiten der Lehmsteine entlang der Mörtelfugen erfolgt. Die numerische Makromodellierung erbrachte zwar befriedigende Resultate hinsichtlich des Spannungs-Dehnungs-Verhaltens, jedoch konnte bei der simulierten Rissbildung keine Übereinstimmung mit den in den Versuchen beobachteten Rissbildern erzielt werden. Bei Lehmsteinmauerwerk ist also eine wesentlich aufwendigere Mikromodellierung notwendig, um das Versagensverhalten korrekt beschreiben zu können.-------------------------------------------------------------------------------------------------------------- Knowledge of the material properties and failure mechanisms of earthen materials is limited and scattered. Within the framework of the NIKER project (www.niker.eu) funded by EC, the mechanical properties of earthen material elements were therefore determined under static compression and shear loads. The aim was to obtain fundamental data on deformation behaviour and failure mechanisms of earthen material structural elements and to describe them by means of a numerical model. The test results confirmed the brittle behaviour of earth block masonry under monoaxial compressive load and showed that the failure of earth block masonry under shear load occurs by sliding of the earth blocks along the mortar joints after initial cracking in mortar joints and earth block. Numerical macro modelling showed satisfying results with regard to stress-strain behaviour, but the simulated crack pattern was not consistent with experimental observations. In the case of earth block masonry, it is thus necessary to use micro modelling approaches in order to correctly predict the failure process at local level.
