In Service Beam Bridge Reliability Assessment

Abstract:

In order to evaluate the reliability of existing bridges ,based on maximum value of the load and model of probability calculation of resistance attenuation, according to the data of the bridge which actually collected, and by using the ADINA finite element software to build the finite element model of considering the damage detection of beam bridge. The component and system failure criteria are determined on the basis of the bridge load-bearing characteristics.The Time-dependent reliability of the system by using the probability calculation model for assessing the maximum value of the load and resistance attenuation can be obtained. The result shows Changes in the process of reliability prediction of bridge , the correctness of reliability calculation model be verified; the correctness of the ADINA model be validated; Also confirmed the feasibility of prediction model; to obtain the main influencing factors of reliability of existing bridges.
