摘要
本文提出一种改进的MorLte—Carlo(MC)法以进行结构的失效概率计算,并将其用于圆柱壳的扭转屈曲可靠性分析。这种改进的MC法可以对某些抽样点不进行结构分析,便可确定其是否位于失效区域之内,从而极大地减少了计算工作量。
An improved Monte-Carlo ( MG) method is proposed for the calculation of failure probability of structure, and it is Used for the reliability analysis of torsional buckling of elastic cylindrical shell. The new MG method can determine some samples whether they are in failure domain without doing structural analysis, so the calculatipn work is decreased
