| Abstract: | In structural design, the reliability-based design optimization (RBDO) has received increasing attention for high reliability and safety. This paper proposes two single-loop methods based on reliability index approach and performance measure approach for RBDO. These two methods directly transform the original RBDO problem into a deterministic optimization. Two well-known RBDO problems are utilized to demonstrate efficiencies of the proposed methods. |
