摘要
根据“投资 -效益”准则 ,提出了基于功能的结构体系目标可靠度优化决策的三种模型 :概念模型、参数规划法模型和约束放松法模型 ;并根据最优性条件 Kuhn-Tucher条件证明了当基于功能的结构体系可靠度约束均为作用约束时 ,参数规划法模型和约束放松法模型的等价性 ;最后对钢筋混凝土框架结构基于不同抗震功能的目标可靠指标进行了优化计算。
The optimal decision model of the target value of performance based structural system reliability is established according to the cost\|effectiveness criterion in the present paper. Three types of optimal decision models are studied, which are conceptual model, parameter programming model and constraint relax model. The parameter programming model and constraint relax model are proved to be equivalent with Kuhn\|Tucher conditions when the performance based structural system reliability constraints are all active. Finally the numerical examples of RC\|frames for different earthquake\|resistant performance are calculated.
