| Abstract: | In this paper,the reliability of structural system is regarded as the control parameter for the optimization design.The significant failure models are identified by using the modified branch and bound method.The reliability of the structural system is evaluated by PNET method.The expressions of sensitivity analysis for strength and stiffness reliability are derived.A optimum vector algorithm is presented to solve the problem of minimum weight design with the constraint of system reliability.The results of evaluated examples demonstrate that the method presented in this paper is effective. |
