摘　　要：现代高层建筑中连体结构日益增多,因为连接体的刚度较小,常采用弱连接的构造方式以减轻地震的耦合效应,使得连体结构可按单体结构进行计算分析。在对比分析了各种弱连接装置后,通过工程实例证明了滑动支座配合黏滞阻尼器的组合减隔震体系在弱连体结构中的适用性。Weak-connection joints is used regularly in connected structure for decreasing the dynamical coupling effect because of the connecting bridge is weak with the more tall building appearance. Then, the weakly-connected structure can be calculated according to the single model. Some weak-connection devices are comparative analyzed in this article. The combinatorial isolation system including spherical steel bearing and fluid viscous damper is proved more practical for such joints than the others by a practical engineering.
