Reliability-Based Optimization of Structural Systems
Abstract
A new objective function for reliability based optimization is suggested which combines partial and total structural failure probabilities in terms of costs assessments. The evaluation of these failure probabilities is based on the failure mode approach while each damage state is approximated by a response surface. Each response surface is used to calculate failure probabilities by applying importance sampling technqiues. The optimization is then performed with respect to preliminary design by defining damage as the formation of plastic hinges. The general formulation of the objective function may be easily adapted to more sophisticated damage models.
