The failure probability of the structures is one of the challenging problems in structural engineering. To obtain the reliability index introduced by Hasofer and Lind, one needs to solve a nonlinear equality constrained optimization problem. In this study, four of the most recent metaheuristic algorithms are utilized for finding the design point and the failure probability of problems with cont...

Structural systems are often subjected to the risk of fatigue-induced failures caused by repeated loadings during their service lifetime (Byers et al. 1997, Karamchandani et al. 1992). The reliability of such structural systems can be sustained through effective structural maintenance as well as proper structural design. It is thus essential to update the reliability of a structure against fati...

This paper examines the application of neural networks (NN) to reliability-based structural optimization of largescale structural systems. The failure of the structural system is associated with the plastic collapse. The optimization part is performed with evolution strategies, while the reliability analysis is carried out with the Monte Carlo simulation (MCS) method incorporating the importanc...
