A Sequential Response Surface Method with Various f and Its Application to Structural Reliability Analysis

A sequential response surface method with various f and a criterion of convergence are proposed for calculation of structural reliability analysis. The method may alleviate the complex function by giving a simple two-order function which can then be used for the reliability analysis. The computing procedure is simplified and the precison of calculation of the reliability is improved. It is suitable for large and complicated structures and can be extended to dynamic reliability analysis.
