Sensitivity analysis of simple random beam models by means of Monte Carlo Methods using Variance Reductions Techniques
Abstract
A probabilistic sensitivity analysis of two nonlinear bar structures is presented. The analysis is carried out on the basis of the Monte Carlo method. The imperfections of the structures and the applied loads are adapted as random variables. Based on all of the generated input variables, an output response of the system is sought. Afterwards, a coefficient responsible for the structure failure is calculated and the limit state histogram is appointed. The shape and the estimators of the histogram make it possible to assess the sensitivity of the selected random variable. This is also performed when the Monte Carlo method variance reductions techniques are applied. The relationship between the behavior of the estimators and the used technique is then observed.
