用引入模糊示性函数的蒙特卡洛方法计算结构的失效概率

Applying the Monte Carlo Method with the Fuzzy Indicator Function to Compute Structural Failure Probability

提出结构的失效除了具有随机性还应具有模糊性的观点，阐明了用模糊示性函数的蒙特卡洛方法计算失效概率的基本原理，从而将各种极限状态统一起来，并使计算所得的失效概率更接近于实际．示例表明，本文方法是完全可行的．

Presents that the structural failure is fuzzy beside random,and introduces fuzzy maths into the Monte Carlo method in order to compute the structural failure probability.Thus,all kinds of upmost limit state have been united.The examples show the suggested method is completely feasible.
