摘要： 用摄动随机无网格伽辽金法(PSEFGM)求解随机结构的响应，然后采用蚂蚁算法对结构可靠性进行了分析。摄动随机无网格伽辽金法具有不需要划分单元和精度高等特点。蚂蚁算法是一种智能型随机搜素优化算法，对目标函数没有任何可微甚至连续的要求，可有效克服经典算法易于陷入局部最优解的常见弊病。数值实例表明，在随机结构可靠性分析方面，随机无网格迦辽金法与蚂蚁算法比经典算法具有明显的优势。

Abstract: This paper starts from applying perturbation stochastic element-free Galerkin method (PSEFGM), which features element-free and high precision, to solve the response of probabilistic structure. And the author analyzes the structural reliability adopting Ant Algorithm. Ant Algorithm is an intelligent optimum algorithm for stochastic searching. This algorithm required no prerequisites of differentiation or even continuation of objective function and can effectively overcome the common disadvantages of classic algorithm-immersing into local optimum. Numerical examples show that the stochasticelement-free Galerkin method and ant algorithm had obvious advantages comparing to classic algorithm in reliability analysis of probabilistic structure.
