Abstract

Time-variant is the typical characteristic of components and systems and the classical approach for time-variant reliability analysis relies on the computation of up-crossing rates. In order to get the up-crossing rate, the common up-crossing approach uses a FORM method to compute the instantaneous reliability index at each time. FORM method likely lead to decrease of the result's accuracy when the limit state function is strong nonlinear. In this paper, a new approach combined PSO with up-crossing approach is proposed to solve this problem and the instantaneous reliability index is computed by PSO. Then a numerical case is carried out to compare this method with up-crossing approach and Monte-Carlo simulation, and the results show that the new approach appears more accurate.
