The stochastic response surface method (SRSM) is widely used in engineering reliability analyses for its efficiency and accuracy. Selection of the collocation points in SRSM is always of great significance, as it may strongly affect the computed reliability results. An improved collocation method that achieves a better tradeoff between efficiency and accuracy is proposed, based on the merits of existing methods. A procedure for step-by-step implementation of the new method is provided. A simple case is employed to test the performance of the proposed method; and a comparative study is conducted to demonstrate advantages of the proposed method with respect to existing collocation methods.
