| Abstract: | To calculate the pipe reliability index, an optimization method was introduced in the paper.Based on the constrained optimization method, a type of inverse model was built up.The theory of reliability inverse problem was used for the analysis of pipe under pressure to demonstrate the application and the efficiency of the method.The result shows that the method is credible and has high precise and rapid calculation.This method can providea reference to the analysis of other structures. |
