A summary of the state-of-practice reveals deficiencies that are addressed by prospective guidance for the anticipated updates of standards, providing a general methodology to obtain cost-optimal decisions using limit state design, probabilistic reliability analysis and cost estimates. The implementation of a draft guideline and the corresponding risk-based approach are illustrated in a full-scale case study dealing with the roof of a stadium located in Northern Italy. The results demonstrate the potential of using monitoring systems and probabilistic reliability analysis in order to support decisions regarding safety measures such as snow removal, or temporary closure of the stadium.}, language = {en} } @inproceedings{HolickyDiamantidisSykora, author = {Holick{\´y}, Milan and Diamantidis, Dimitris and S{\´y}kora, Miroslav}, title = {Effects of Quality Control on Reliability of Reinforced Concrete Structures according to Eurocodes}, series = {fib Symposium 2016 : Performance-Based Approaches for Concrete Structures, 14, 2016, Cape town}, booktitle = {fib Symposium 2016 : Performance-Based Approaches for Concrete Structures, 14, 2016, Cape town}, abstract = {The effect of quality control on structural reliability represents an increasingly important concern of designers and thus is investigated in this contribution, focusing on reinforced concrete structures. Recent European documents for structural design - Eurocodes, fib Model Code 2010 and ISO 2394:2015 for general principles on structural reliability indicate that the partial factors may be adjusted to available information on the quality control of structures. In particular, the partial factors for concrete and steel strength may be significantly reduced taking into account actual execution quality and related available data. Using probabilistic methods of structural reliability, effects for execution quality are investigated in this contribution considering two fundamental reinforced concrete members: a beam (or slab) exposed to bending and a short column exposed to compression. It is shown that the reliability of reinforced concrete members may vary with the load ratio of variable and permanent actions. It appears also that the structural members of a basic quality, designed using unreduced partial factors, have a greater reliability level than the members of an increased quality, designed using the partial factors reduced according to EN 1992 1 1. This provides the basis for recommendations for further code developments.}, language = {en} } @inproceedings{SykoraDiamantidis, author = {S{\´y}kora, Miroslav and Diamantidis, Dimitris}, title = {Snow Load Monitoring - Measure to Control Reliability of the Roof of a Stadium}, series = {International Conference Structural Reliability \& Modelling in Mechanics, 24.-25.05.2018, Ostrava, Czech Republic}, booktitle = {International Conference Structural Reliability \& Modelling in Mechanics, 24.-25.05.2018, Ostrava, Czech Republic}, abstract = {This contribution shows how monitoring can be used to control reliability of a structure not complying with the requirements of Eurocodes.
