An Effective Method for Exact Reliability Analysis

Seifedine Kadry and Khaled Smaili

Abstract:
In this study, an effective method, we called PTM-FEM, is proposed to evaluate the probability of failure in analytical form, instead of approximation methods like FORM/SORM, no series expansion is involved in this expression. This method is based on the Finite Element Method (FEM) to get the expression of the response of stochastic systems then to linearize step-by-step this expression and finally to apply the probabilistic transformation method (PTM) of random variables to obtain the probability density function of the response. After that, the computation of the failure probability is straightforward. An application of 25-bar truss structure is provided to illustrate this method.
