Application of soft computing techniques for reliability calculation of time demanding problems
Original language description
The reliability analysis of complex structural systems requires utilization of approximation methods for calculation of reliability measures with the view of reduction of computational efforts to an acceptable level. In the paper, an artificial neural network based response surface method in combination with the small-sample simulation technique is presented. An artificial neural network is used as a surrogate model for approximation of original limit state function. Efficiency is emphasized by utilization of the stratified simulation for the selection of neural network training set elements. Response surface obtained is independent of the type of distribution or correlations among the basic variables which enables sensitivity studies with respect to these parameters without much computational effort. Subsequently, the ANN surrogate model is utilized in conjunction with Monte Carlo simulation method to obtain desired reliability measures. The proposed method is tested using nonlinear limit state function taken from the literature as well as employed for reliability assessment of concrete bridge.
