【摘要】 综合考虑结构中多种不确定因素的影响,提出采用蒙特卡洛法进行结构可靠度预计。蒙特卡洛法结构可靠性分析是通过随机模拟和统计试验来求解结构可靠性的近似数值方法。在应用该方法时,需要处理大量的统计试验数据,若采用人工处理会有很大的困难。现将随机可靠性理论与有限元求解方法结合,利用蒙特卡罗法对无法写出显式功能函数的复杂结构进行结构可靠度预计,并得到相应可靠度。更多还原

【Abstract】 Considering the effect of multiple uncertain factors,this paper proposes that Monte Carlo method is used to predict the structural reliability and according to it,evaluates its safety. This is an approximate numerical method of calculating reliability by random simulation and statistical testing. A large number of statistical test data needs to be handled in the use of this methed. It is extremely difficult to process the data manually. Thus,random reliability theory and finite element method are integrated in this paper.The reliability prediction of complex structure is approached with Monte Carlo method,which cannot be written in the form of explicit function. Correspondingly,the reliability is predicted.更多还原
