| 摘 要： | 利用抗震结构的多目标优化设计理论，同时考虑延性及结构自振周期，对钢筋混凝土结构造价最低和延性最好的两个目标函数进行优化设计，按照现行的《混凝土结构设计规范》及《建筑抗震设计规范》建立了数学模型；并根据ＧＢＪ１１－８９给出的４类场地的特征周期，计算了钢筋混凝土框架结构的算例。结果表明，在抗震结构优化设计中，同时考虑结构的延性和结构的自振周期有利于结构的抗震。

| Abstract: | The multiobjective optimization design of seismic structures considering structural vibration period restraint and ductility is studied in this paper, using the theory of multiobjective for seismic structures. Mathematical model which is compiled with both codes of Concrete Structure Design (GBJ10-89) and Seismic Constructure Design (GBJ11-89) is set up. The examples of reinforced concrete structure are calculated according to the feature of four types of field provided by GBJ11-89. Results show that the presented method is helpful to earthquake resistance of the structure. |
