| Abstract |
Probabilistic analysis is rapidly developing into a desirable tool to improve design processes. Incorporating probabilistics with optimization of structures is a step towards improving many current deterministic design systems. This paper deals with applications of two optimization techniques to solve reliability based optimization problem of structures. The reliability based optimization problem is formulated as minimization of structural volume subject to the constraints on the values of componential reliability indices determined by AFOSM approach. This presented method may be an useful tool for the reliability-based design optimization of structures. |
