摘　　要：采用有限元软件SAP2000对一钢框架-剪力墙结构的换流站阀厅在罕遇地震作用下的非线性动力性能进行分析。计算过程中,分别使用了三条典型地震波,最后分别得到了柱顶位移、柱底力及索轴力的时程曲线。计算结果表明,在罕遇地震作用下,结构位移可满足规范的要求,但索轴力和柱底力的增幅均较大,在设计时应给予重视。The non-linear time-history analysis of steel frame-shear wall structure of the valve-hall was presented ,three typical seismic waves were used and the analysis of the valve-hall was accomplished by using the finite element software SAP2000 .Finally ,the time-history of top of the column displacement ,bottom of the column force and axial force of the cables were obtained .The results indicate that the seismic performance of the valve-hall can satisfy the criterion of the seismic code in rare earthquakes But the bottom of the column force and axial force of the cables were highly increased in the analysis ,so more attention should be given to the design regarding to this .
