An improvement of the response surface method based on successive linear interpolation

摘要：

　　The response surface method (RSM) is widely used to alleviate the computational burden of engineering analyses.For reliability analysis,the common approach in the RSM is to use a linear interpolation technique.However,the experimental points are all arranged using the classical RSM in each process of interpolation.Therefore,the number of experimental points is large that resulting in the efficiency is lower.In this study,an improvement of the RSM for structural reliability analysis has been proposed based on the technique of successive linear interpolation.As seen from the example,the proposed method yields better results than those of the classical RSM,and the number of experimental points using the proposed method is less than that of classical RSM.It seems that the proposed method improves the convergence speed and reduces the computational effort.
