［摘要］塔裙一體結(jié)構(gòu)地震響應(yīng)研究對(duì)于塔裙方案抗震分縫策略、塔樓抗震設(shè)計(jì)方法有重大意義。以塔裙一體結(jié)構(gòu)為研究對(duì)象，從裙房剛度和裙房塔樓樓層質(zhì)量比兩個(gè)因素入手，詳細(xì)分析了裙房剛度和裙塔樓層質(zhì)量比對(duì)于塔樓地震響應(yīng)的影響。分析結(jié)果表明，裙房剛度和裙塔樓層質(zhì)量比對(duì)于塔樓地震響應(yīng)影響十分明顯；結(jié)構(gòu)抗側(cè)剛度除了與結(jié)構(gòu)布置自身相關(guān)以外，與樓層質(zhì)量分布也具有相關(guān)性。對(duì)于塔裙一體結(jié)構(gòu)而言，塔樓的抗震設(shè)計(jì)十分關(guān)鍵，需要采取塔樓單獨(dú)計(jì)算和塔裙一體計(jì)算包絡(luò)分析方法。

Abstract:The study of seismic response of tower-podium integrated structure is of great significance to the strategy of seismic joint separation of tower-podium scheme and the seismic design method of tower building. Taking the tower-podium integrated structure as the research object, the two factors of the podium stiffness and the tower-podium floor mass ratio were used to study the influence of the podium stiffness and the tower-podium floor mass ratio of the podium tower on the seismic response of the tower in detail. The analysis results show that the stiffness and tower-podium floor mass ratio have a significant impact on the seismic response of the tower, and the lateral stiffness of the structure is related not only to the structural layout itself, but also to the mass distribution of the floor. For the tower-podium integrated structure, the seismic design of the tower is very important. It is necessary to adopt the envelope analysis method to consider both the calculation of tower-podium integrated structure and the calculation of the tower alone.

Keywords:tower-podium integrated structure; lateral stiffness of structure; floor mass ratio; floor seismic shear
