| 摘 要： | 遗传算法作为一种优化算法,对目标函数和约束条件没有过于苛刻要求,在结构可靠度计算中的应用越来越广泛.利用MATLAB数学软件,并引入遗传算法编制相应程序,对提供的已知功能函数进行了可靠度计算,同时,考虑各种不确定因素对桁架体系的结构可靠度也进行了研究,计算效果较好,表明该方法在可靠度特别是复杂体系可靠度分析中应用价值较为突出.

| Abstract: | As an optimization technique,genetic algorithm has no exacting terms for objective function and constratint condition,and the application of GA to structural reliability analysis is more and more comprehensive.By virtue of the MATLAB-based genetic algorithm toolbox programed 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.It indicates that this method has an outstanding use value for reliability analysis and especially for complex structure reliability analysis. |
