| 摘 要： | 利用ANSYS有限元分析软件自带的概率设计系统(PDS)中的响应面法,对某一实际工程中的高桩墩式码头进行了三维有限元分析,得到结构的响应面方程。再利用Matlab软件结合验算点法(JC法),通过迭代搜寻验算点,最终求得了结构在各项外部荷载及其自身重力作用下的结构可靠性指标。由于结构的极限状态方程未知J,C法无法正常使用。根据ANSYS中响应面法的计算原理,采用了一种新的方法将上述荷载正态当量化。此外,还进行了高桩墩式码头可靠度的敏感性分析,得到了敏感性因素。计算结果与实际情况符合较好,可为高桩墩式码头的结构设计校核提供参考依据。

| Abstract: | Three dimensional finite element analysis was made for pile pier according to response surface method,which was one of the PDS method in ANSYS,and the response surface equation was obtained.Then the reliability index of the structure under various external loads and its gravity was calculated by searching the check point iteratively with the Matlab software and JC method.Because the limit state equation was unknown,JC method could not be used.A new method was used to normalize the design variable according ... |
