| 摘 要： | 将多目标优化方法应用于钢筋混凝土抗震结构中，同时考虑结构的造价最低和塑性最好的两个优化目标，简便地处理了结构位移延性和构件曲率延性之间的关系。按照现行的《建筑抗震结构设计规范》ＧＢＪ１１－８９和《混凝土结构设计规范》ＧＢＪ１０－８９建立了数学模型，计算了４层框架结构的算例。结果表明，本文提出的理论及计算方法是合理的。

| Abstract: | The new theory of multiobjective optimization design of seismic structures is studied in this paper. Two objectives: the maximum of the structural ductility index and the minimum of the total structural cost which firstly be introduced into optimal design are considered. A simple relation between displacement ductility index and curvature ductility index is derived. A mathematical model is complied according to both codes of Concrete Structure Design(GBJ10 89) and Seismic Constructure Design (GBJ11 89). Finally, examples of reinforced concrete structure are calculated. Results show that the theory of multiobjective optimization design for reinforced concrete structure under seismic load is rational. |
