从蒙特卡罗方法的思路可看出，该方法回避了结构可靠度分析中的数学困难，不管状态函数是否非线性、随机变量是否非正态，只要模拟的次数足够多，就可得到一个比较精确的失效概率和可靠度指标-Ideas from the Monte Carlo method can be seen that this method avoided the structural reliability analysis of the mathematical difficulties, regardless of whether the nonlinear state function, random variable is non-normal, as long as the number of simulated multi-enough, you can get a more precise failure probability and reliability index
