Evaluating seismic reliability of Reinforced Concrete Bridge in view of their rehabilitation
Structure LGCE l’EST, Salé-CED de l’EMI, Mohammed V University in Rabat-MOROCCO
Considering in this work, a simplified methodology was proposed in order to evaluate seismic vulnerability of Reinforced Concrete Bridge. Reliability assessment of stress limits state and the applied loading which are assumed to be random variables. It is assumed that only their means and standard deviations are known while no information is available about their densities of probabilities. First Order Reliability Method is applied to a response surface representation of the stress limit state obtained through quadratic polynomial regression of finite element results. Then a parametric study is performed regarding the influence of the distributions of probabilities chosen to model the problem uncertainties for Reinforced Concrete Bridge. It is shown that the probability of failure depends largely on the chosen densities of probabilities, mainly in the useful domain of small failure probabilities.
Key words: Reliability / ANOVA / Nonlinear / Analysis of variance / finite element method / ANSYS
