本文利用抗震结构的多目标多级优化设计理论，对考虑结构自振周期约束的抗震结构优化设计进行了研究，并根据规范ＧＢＪ１１－８９给出的四类场地的特征周期，计算了剪切型钢框架的算例。结果表明，在抗震结构优化设计中考虑结构自振周期约束有利于结构的抗震。
In this paper, the multi-objective multi-stage optimal design theory of seismic structure is used to study the optimal design of seismic structure considering the natural period constraints of the structure. According to the characteristic cycle of the four types of site GBJ11-89, shear steel is calculated. An example of a framework. The results show that considering the structural self-vibration cycle constraint in the optimal design of seismic structure is beneficial to the seismic resistance of the structure.
