摘要
A response surface method using moving least square method is applied for structural reliability analysis in this paper. In each iteration, sampling point's weight is redefined by not only the distance between the point and center point but also the distance between the point and response surface. Meanwhile, current iteration's influence domain is transformed according to the last response surface obtained from former iterations. Thus, an improved moving least method is proposed and numerical results indicate the improved method has higher accuracy.
