A Critical Study on the Haldar and Mahadevan's Reliability Analysis

Mahadevan and Haldar has developed reliability analysis method which is presented in their book: Reliability Assessment Using Stochastic Finite Element Analysis (2000). They use Stochastic Finite Element Method, as an input to explicit performance function required by FORM (First Order Reliability Method) and SORM (Second Order Reliability Method). This method is claimed to have been verified using Direct Monte Carlo simulation and the results are satisfactory. This paper presents a comparison of Haldar and Mahadevan's Method and Wisudawan Method which is based on Direct Monte Carlo Simulation and Finite Element Method. The comparison shows that there is a large different result. However Direct Monte Carlo Simulation is most accurate method, while FORM and SORM has been criticized by previous researcher because of the less accurate result in some cases. This paper recommends for Haldar and Mahadevan also other researchers to increase the accuracy of the method.
