| 摘 要： | 对Ｒｏｓｅｎｂｌｕｅｔｈ方法提出了改进措施，使改进后的Ｒｏｓｅｎｂｌｕｅｔｈ方法可以较精确求得功能函数的前四阶概率矩．应用最大熵法拟合功能函数的概率密度分布，从而求解极限状态方程的失效概率．本法对复杂不易求导和工程中常见的隐函数表达的极限状态方程的可靠度分析十分简便

| Abstract: | The Rosenblueth method is adapted in order to calculate the first four probability moments of state function exactly. The probability density function is generated based on the maximum entropy theory to get the failure probability of the limit state equation. It is convenient to use the present method to deal with complex and close form limit state equation in reliability analysis. |
