摘　　要：户内式变电站由于电气设备工艺的要求,表现为典型的非对称结构形式。以往对该类变电站结构进行地震响应分析时常采用反应谱分析方法,仅考虑单向地震波输入时的情况,采用地震时程分析方法并考虑材料的非线性因素,对某变电站结构在多维地震作用下的非线性动力反应进行研究,并把计算结果与单向地震作用的结果进行分析比较。所得结论可为同类电力建筑物的抗震设计提供建议和参考。The style of substation-indoor is asymmetric because the need of electric equipment. It is usually used response spectrum method to analyse earthquake action of substation, which can simplify the calculation. In order to compare the results of earthquake wave between one direction input and multiple direction input, on the base of former researches, non-linear time history analysis used to study seismic response of substation under multiple-dimensional earthquake action and some useful conclusions are obtained. The results can provide some advice and reference for the seismic design of similar electric power buildings.
