［提要］  利用耗能减振技术连接不同高度、不同质量、不同刚度的主楼与裙房，在国内尚无工程实践。世茂国际广场裙房结构刚度中心与质量中心存在严重的偏心，设计采用40个粘滞流体阻尼器将其与主楼连成整体。通过结构整体弹塑性分析，表明连接解决了裙房的偏心问题，而且粘滞流体阻尼器能够实现结构各阶段的抗震目标，在风荷载作用下它也能起到连杆及部分耗能的作用。

Design on Weak Connection Between Main Tower and Podium in Shanghai Shimao International Plaza/Wang Dasui, Zhang Jian (East China Architecture Design Institution, Shanghai 200002, China)
Abstract:It is the first example to adopt damper connection in different height, stiffness and structural types of buildings in China. There existed a large eccentricity between the stiffness center and the mass center at the podium of Shimao international plaza. Total 40 liquid dampers are used to connect the podium to its tower. By nonlinear analysis of the whole structure, the problem is solved. This connection can not only meet seismic design goals but wind load as well.
