| Abstract: | The respective characteristics between Monte Carlo method and response surface method were compared,and in the process of reliability analysis of Chongqing Jiangbei Airport cast steel joints,response surface method was chosen to carry out relevant research.Selecting a certain input and output variables of three-branch-edge cast steel joints and three-branch-middle joints in Chongqing Jiangbei Airport,the response surface equation can be fitted by means of parametric modeling.Then the Monte Carlo simulation is processed in response surface,finally,the reliability of the cast steel joints was analyzed and evaluated based on the output of PDS post-processing. |
