| Abstract: | Monte Carlo finite element method is combining the structural analysis with the statistic analysis of PDS module by APDL language resulted from the large-scale standard finite element program ANSYS.The implementation process of the Monte Carlo Method is described in detail by a case of A-type derrick structure reliability analysis.The failure probability and the reliability index β of the A-type derrick are obtained,which shows that the method can be used for the reliability analysis of a structure. |
