摘    要:建立了结构生命期内的设计优化模型。根据该模型,不仅可以得到结构的最优设计-维修策略,而且可以得以结构的寿命期。对在役结构,给出当前结构的剩余承载力,模型将给出结构以后的最优维修决策。该模型的优点在于理论简单易懂,计算方便,便于实际应用。

关 键 词:全过程设计优化  生命期折算总费用  经济生命期  承载力衰减

Abstract:An optimal integrated design is referred to as the trade off between a structural initial design and its maintenance policy over a design lifetime. Unfortunately. few overall models for integrated design optimization exist currently. This paper aims at establishing an integrated design optimization model for any calculated structures. With the model, the optimal design parameters and corresponding maintenance strategies for a structure can be determined leading to the minimum total discounted lifetime cost. This model differs from others in that it uses deterministic mathematics, other than stochastic process and reliability theory, as a basis. Compared to other models, the advantages of this one lie in its theoretical simplicity, computational tractability, and strong practicability.
Keywords:integrated design optimization  discounted lifetime cost  economic service life  resistance deterioration
