Abstract:
In order to analyze the life of the bridge structure, based on Monte Carlo reliability calculation method, using the ANSYS program to establish material properties change in variables and load characteristic variables, which based on time as the basic variables, the obeyed distribution patterns, the structure of the bridge resistance and load model are presented to obtain the bridge structure stress and deformation by calculation, then through the criteria for judging the reliability of two bridges to calculate the bridge reliable operation probability at different times, thus the time-reliable probability curve can be driven, with which the reliable probability can be gotten directly from the diagram on the different period. 6 tabs, 8 figs, 8 refs.
