摘要
本文以文献中提出的结构体系可靠度分析的最弱失效模式法为基础,充分考虑结构体系的造价和结构的损失期望与结构体系可靠度的关系,以及结构构件的可靠度约束,提出了结构体系目标可靠度的优化决策方法;基于优化决策的结果,提出了结构体系的最优设计准则;最后,依所提出的最优设计准则,实现了高层建筑基于构件和结构可靠度约束的结构优化设计。
Based on the weakest failure mode method for the reliability analysis of structural systems presented in our previous paper [1, 2] , on optimum decision method for reliability target values of structural systems in presented by full considering the relation between structural systems reliability and the construction cost and expected loss of structural systems, also the reliability restraint of structural components. Based on the result of optimum decision, the optimum design formulations of structural systems are presented. Finally, based on the optimum design formulations, the optimum design of tall buildings based on reliability restraint of structural components and structural systems is realised.
