协调维护和失效损失的结构优化设计

STRUCTURAL OPTIMUM DESIGN BALANCED WITH FAILURE DAMAGE AND NORMAL MAINTENANCE

摘要: 本文建立了一个考虑结构在使用阶段内因结构失效导致的经济损失和正常维护费用的总费用模型,讨论了基于此模型的结构最优设计。本文从总费用角度给出了一个确定合理的结构体系失效概率P_f的途径,提出了在结构设计中应考虑使用阶段正常维护的结构优化设计思想。

Abstract: In this paper, a structural total cost model is established which considers normal maintenance and failure damage in its service life. And a structural optimum design based on this model is discussed. An approach for determination of proper structural system failure probability based on this model this total cost model is presented and a concept of structural optimum design balanced with normal maintenance in its service life is proposed.
