摘　　要：为研究带有连体的大底盘双塔结构在竖向地震作用下的反应情况,确定连体的合适位置,本文应用ANSYS软件建立三个比对模型,并分别对它们进行了Z向的地震加速度反应谱分析,通过分析得到了这三个模型的整体变形情况、最大位移曲线,并将之进行比较,得出了相应结论,即带有连体的大底盘双塔结构在竖向地震作用下整体变形和位移明显加大,并且随着连体位置升高,作用效果更加明显.With Twin Towers and large chassis structure integrated damage more serious,even under the action of vertical earthquake.Reaction on Twin Towers and large chassis connected with structure under vertical seismic action and determine the appropriate double,this paper applied the ANSYS software to establish three comparison model,and analyze earthquake acceleration response spectrum of Z direction,by analysis,It is obtained that the overall situation of the deformation of the three models,the maximal displacement curve,and the comparison,the corresponding conclusion with large chassis conjoined twin towers structure under vertical earthquake in the overall deformation and displacement increase obviously,and with increasing conjoined position,effect more apparent.
