Study of systeme redundancy in bridges : failure machanism analysis using response surface methods

Abstract : In this thesis, a system redundancy analysis for reinforced concrete bridges has been presented. This analysis is performed in order to appraise the load redistribution effects based on a serviceability requirement of excessive deformation. In order to specify the effects of damage in both the bridge serviceability and the individual components serviceability, several damage scenarios have been considered. In order to consider uncertainties related to the various parameters, calculations are carried out through a probabilistic approach. Traditional techniques of the theory of reliability allow today to calculate in various manners, the failure probability of the specific failure modes associated to the individual components, subject to have a probabilistic characterization of the variables and an explicit limit state. Reality is however different. For complex structural systems, it is almost impossible to get explicit limit states. Limit state function can be evaluated only by calculations, in particular with finite element analysis are often called
