遗传算法（GA）作为一种优化算法，用于结构可靠度分析，对目标函数和约束条件没有过于苛刻要求，利用MATLAB软件，引入遗传算法编制相应程序，验证已知功能函数的结构构件的可靠度。工程实例计算表明，结合遗传算法分析结构体系可靠度，不受搜索空间的限制性假设的约束，不要求目标函数具有连续性、可导等假设，其结果与其他算法结果具有一致性。

As an optimization technique, genetic algorithm has no exacting terms for objective function and constraint condition, by virtue of the MATLAB - based genetic algorithm toolbox programmed by Sheffield University, this paper does research on the reliabilities for provided performance functions and a truss structure taking into account uncertain multifactor, and it has an good effect. In this paper, the genetic algorithms is used for solving the structure reliability, form the search of the restrictive assumption constraints, not the objective function is continuous, differentiable hypothesis, the consequence of genetic algorithms compared with the method of JC, and display the genetic algorithms in the structure reliability in the calculation of the advantages.
