[摘要] 工程主体结构高65. 6m，采用钢筋混凝土框架．核心筒结构，由于宿迁地处高烈度抗震设防区，依靠单纯“硬抗”的传统设计，无法满足该工程的抗震设计要求，因此，拟采用设置非线性粘滞流体阻尼器的消能减震装置。采用SAP2000对是否采用粘滞流体阻尼器的结构进行了罕遇地震作用下的动力弹塑性分析。计算结果表明，采用了粘滞流体阻尼器结构的层间位移角和基底总剪力均满足规范要求，减震效果明显。

Abstract: The project is a reinforced concrete frame-core tube building with a height of 65.6 metres.  Because Suqian is located in high intensity earthquake fortification zone, relying solely on "resist" traditional design, can not satisfy the engineering seisnuc design requirements, therefore, the set of nonlinear fluid viscous damper energy dissipation device was adopted. The dynamic nonlinear analysis of the building under major earthquake was camed out by SAP2000 which the building take the fluid viscous damper or not. The results show that inter storey drifts and total base shear of building which take the damper can satisfy the code requirements. The effect of seismic reduction is obvious.
