摘要
随机差分法就是把概率统计方法同差分法相结合的分析计算方法。本文对梁的随机差分计算方法进行了分析,建立了可靠性分析的极限状态方程,考虑荷载,截面几何尺寸的随机特性,编制了相应的计算程序,首次提出了用随机差分进行结构可靠度分析的基本方法。
To analysis structural reliability by probability method is a new devel-opment in structure design.This paper has detailed a new way at beamprobability analysis,that is the combination of probable method and finitedifference method.Equations of limiting condition have been established,in which the random characteristic of loads and cross section has been cons-idred,appropriate calculating program has been drawn up.It is the firsttime to analysis structure reliability by the random finite difference method.
