| 摘 要： | 采用SAP2000程序建立了某4层框架结构加两层钢框架后的有限元模型,对该加层框架结构在设置阻尼器前后进行罕遇地震作用下的时程分析对比。结果表明,设置了阻尼器后增加了结构的耗能能力,达到了对结构振动控制的目的,并且比较精确地反映了设置粘滞阻尼器后该结构地震反应的实际,是一种较为实用和精确的计算方法。

| Abstract: | A finite element model for a frame structure with six floors after adding two storeys on top of it is set up by using SAP2000.By analyzing and comparing for the frame structure,it is shown that the viscous damper can enhance the structure's aseismic capacity,control the structure's vibration and accurately reflect the seismic response of the structure.It is a practical and precise calculating method. |

| Keywords: | finite element viscous damper exceptionally strong earthquake control effect |
