Abstract
This study proposed a benchmarking method by performing structure reliability analysis of the competitor’s leading products. Such analysis was performed by an improved response surface method. This improvement aimed to reduce the computational effort involved in the reliability analysis. For the structure reliability analysis of large-scale structure without an explicit expression, the MATLAB-ANSYS co-calculation was applied to get the explicit response surface function (RSF) as a surrogate model to approximate the implicit limit state function (LSF). After obtaining the RSF, the genetic algorithm (GA) and traditional JC method (a geometric algorithm, recommended by the Joint Committee on Structural Safety) were used to calculate the reliability index and design point, respectively, for comparison. The results showed that using MATLAB-ANSYS co-calculation to obtain the RSF was easy to implement and that the GA could improve calculation efficiency by more than 90%. The result was also verified by the classical Monte Carlo simulation (MCS) in ANSYS PDS. This study provides an easy and efficient way to perform the competitor benchmarking of the market leaders’ product by reliability analysis. This method can be used in any structure design for the company who is the market follower.
