Abstract

Structural reliability refers to the probability of structure perform its required functions under stated conditions for a specified period of time, Monte Carlo method and response surface method are used to analyze the structural reliability combine with a example, the feasibility of analyzing reliability with ANSYS software is verified, advantage of response surface method is shown by comparison. Taking a standard long-span prestressed girder bridge for the analysis object, this paper analyzed reliability of structural system in a variety of failure modes and the sensitivity of factors. Further considering the resistance of bridge declined over time, analyzed the time-dependent reliability of bridge system and predicted service life of bridges.
