Weighted Linear Response Surface Method for Structural Reliability Analysis

Abstract

Response face method is a common method to do reliability analysis for uncertain expressed complex structures of limit state function. This thesis introduces a weighing linear response surface method on the base of traditional response surface method. This method mainly chooses good sample points, and gives up bad sample points by the way of giving the point rational weight number in order to raise the fit precision. Then the thesis presents the calculation steps and flow chart of the weighing linear response surface method. Finally, it inspects and verifies the superiority of the new method through a count case on fit precision.
