Abstract

The structural reliability means the probability of structure to accomplish the prearranged capability in required time and conditions. In this paper, firstly, taken a board structure and completed its structural reliability analysis respectively with the Monte-Carlo and response surface method, which verified the feasibility for probability design in ANSYS, and the advantages of response surface method. Then, considered the reinforced concrete simply supported girder bridge as the research object, the space entity model for finite element analysis was established with the uncertainty of the material features and the geometrical dimensions, and then analyzed the structural reliability of the ultimate carrying capacity by response surface method. Compare the sensitivity of the random variables, that is, the effection of probability distribution parameters to the probability of failure.
