【摘要】 针对工程人员在进行结构可靠度分析时不能选择最佳的计算方法的问题,采用分类比较的方法,系统分析了计算可靠度的基本方法：一次二阶矩法、高次高阶矩法、响应面法、蒙特卡罗法、优化法、随机有限元法。概括了每一种计算方法的特点及优缺点,指出了它们的适用条件和应用范围,为工程人员选用合理的方法进行结构可靠度计算提供一个有价值的参考。更多还原

【Abstract】 In view of the problem that engineers can not select a best computation method when analyzing structural reliability,adopting group comparison method are systematically analyze,the basic reliability computation methods are systematically analyzed including simple second moment,high order moment method, optimized method,response surface method,Monte-Carlo method,stochastic finite element method.The merits and demerits of various methods are summed,and their application condition and applied range are pointed out.The results supply important references for engineers selecting rational reliability computation methods when analyzing structural reliability.更多还原
