摘　　要：为研究双塔连体结构在地震下的各项抗震性能,利用SAP2000软件分别建立了加入X型支撑的两种模型,对模型进行模态、反应谱分析和在选定的3种地震波下时程分析,结果表明,加入支撑后结构的自振周期明显降低,抗扭刚度得到提高,且添加支撑及相同支撑添加在结构的不同位置都有利于减小结构的层间位移和位移角,说明加入支撑能够提升结构的抗震性能。In order to study the seismic performance of the twin tower connected structure under earthquakes,two models with X-shaped supports were established using SAP2000 software.The models were subjected to modal,response spectrum analysis,and time-history analysis under three selected seismic waves.The results showed that the natural vibration period of the structure was significantly reduced and the torsional stiffness was improved after the support was added,Moreover,adding support and adding the same support at different positions in the structure are beneficial for reducing the inter story displacement and displacement angle of the structure,indicating that adding support can improve the seismic performance of the structure.
