Multicriteria reliability-based structural optimization
Abstract The paper addresses the problem of efficiently designing structural systems subject to reliability constraints imposed at both serviceability and ultimate limit states. The serviceability performance constraint ensures acceptable safety level against first plastic hinge occurrence, while the ultimate performance constraint ensures adequate safety against plastic collapse. The multicriteria reliability-based optimization problem with unserviceability and collapse as the failure criteria is presented for different optimum design formulations. The optimization is performed by using the feasible directions method. It is concluded that multicriteria reliability-based optimization has substantial potential for application in optimal design of structural systems.
