Abstract

Reliability-based Topology optimization (RBTO) is used to obtain an optimal topology satisfying given constraints, as well as to consider uncertainties in design variables. Most real structures are subjected to different load at different time. This is referred to as multiple load cases. Topology optimization for multiple load cases can consider loads applied at the same time or at different times (by using weight factors). This article presents an approach for RBTO using multiple load cases. The optimal topology obtained by two method in multiple load cases is compared and also the topology obtained by RBTO compared to that obtained by deterministic Topology optimization (DTO). The results show that optimal topology obtained through weight factors is more stable than another method when only one load is applied.
