[摘要] 工程主體結(jié)構(gòu)高65. 6m，采用鋼筋混凝土框架．核心筒結(jié)構(gòu)，由于宿遷地處高烈度抗震設(shè)防區(qū)，依靠單純“硬抗”的傳統(tǒng)設(shè)計(jì)，無(wú)法滿足該工程的抗震設(shè)計(jì)要求，因此，擬采用設(shè)置非線性粘滯流體阻尼器的消能減震裝置。采用SAP2000對(duì)是否采用粘滯流體阻尼器的結(jié)構(gòu)進(jìn)行了罕遇地震作用下的動(dòng)力彈塑性分析。計(jì)算結(jié)果表明，采用了粘滯流體阻尼器結(jié)構(gòu)的層間位移角和基底總剪力均滿足規(guī)范要求，減震效果明顯。

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.
