摘　　要：结合黄屯110 kV变电站生产综合楼设计实例,在结构-电气设备复合体系中考虑二者相互动力作用,分析复合体系在大震弹塑性阶段的地震响应,并与不考虑相互作用的计算模型比较分析。分析结果表明,在大震作用下,电气设备参与整个复合体系的动力反应,使主结构的地震响应变大,同时电气设备本身的动力作用也变大,如仍采用传统的等效荷载法设计是偏不安全的,最后给出主结构和电气设备抗震设计的合理建议和优化措施。A nonlinear dynamic response analysis with structure-equipments interaction of an integrative building in 110 kV Huangtun substation is studied.The results are compared with that of no structure-equipments interaction,which show it is necessary to considering structure-equipments interaction in integrative building of indoor substation.Under rare earthquake,the structure-equipments interaction should be considered,because the seismic responses of structure and equipments with consideration of the interaction are larger than those without consideration of the interaction.In this condition,the traditional equivalent load method will be insecure anymore.In the last,some optimization measures and reasonable suggestions about seismic design of structure and equipments are introduced.
