| Abstract: | First, a perturbatin stochastic element -free galerkin method (PSEFGM) that has charcters of high precise and element - free is applied to solve the response of probabilistic structure in this paper. Second, the structural reliability has been analyzed by genetic algorithm. Genetic algorithm is an intelligent searching optimum algorithm. Numerical example shows that the stochastic meshless Galerkin method and the genetic algorithm have obvious advantages and wide prospects of application in reliability analysis of probabilistic structure. |
