［摘要］戶內(nèi)式變電站由于電氣設(shè)備工藝的要求，表現(xiàn)為典型的非對(duì)稱結(jié)構(gòu)形式。以往對(duì)該類(lèi)變電站結(jié)構(gòu)進(jìn)行地震響應(yīng)分析時(shí)常采用反應(yīng)譜分析方法，僅考慮單向地震波輸入時(shí)的情況，采用地震時(shí)程分析方法并考慮材料的非線性因素，對(duì)某變電站結(jié)構(gòu)在多維地震作用下的非線性動(dòng)力反應(yīng)進(jìn)行研究，并把計(jì)算結(jié)果與單向地震作用的結(jié)果進(jìn)行分析比較。所得結(jié)論可為同類(lèi)電力建筑物的抗震設(shè)計(jì)提供建議和參考。

Abstract: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.
Keywords:multiple-dimensional earthquake action; electric power buildings; asymmetric-plan structure; non-linear time history analysis；coupling response
