Abstract: A reliability‐based optimization sensitivity analysis technique based on the feasible directions concept is presented for plastic design of redundant structures. This technique is specialized to a formulation of the problem ...

Abstract: An overview of the major concepts and methods used in reliabilitybased structural optimization is presented. New formulations related to multicriteria optimization are developed. Comparative results are presented when ...

Abstract: This paper addresses the stochastic modeling for advanced jet engine applications and also presents an overview of the basic theoretical aspects of different useful stochastic field models and then illustrates their ...

Abstract: This paper proposes a novel optimal condition-based life-cycle highway bridge maintenance framework incorporating decision makers’ risk perceptions. The inspection and repair planning are formulated as a multiobjective ...

Abstract: In order to ensure structural safety, deteriorating bridges should be maintained above their target reliability level. This level affects the optimum maintenance interventions during the service life of a bridge. Therefore, ...

Abstract: The risk-based approach is a powerful tool to assess the impact of hazards on bridge networks. The results of risk analysis of a bridge network can be integrated into an optimization process to obtain the optimal maintenance ...
