【摘要】 对薄弱层设置粘弹性阻尼器(VED)支撑的钢框架进行了地震模拟振动台试验研究.试验中设计制作了一个五层钢框架模型,对纯钢框架结构、仅设钢支撑的钢框架结构及第一层、第三层和第五层分别设置粘弹性阻尼器支撑的结构进行了罕遇地震和多遇地震下的振动台模拟试验,并与有限元分析结果进行了对比.结果表明,粘弹性阻尼器能够有效控制结构的地震反应,但罕遇地震下的减振效果较多遇地震下的减振效果有所降低.更多还原

【Abstract】 The vibrating table tests about the steel frame whose weak layers equipped with viscoelastic dampers(VED) are performed.A five-floor steel frame model is designed and constructed,which is equipped with viscoelastic dampers on the 1st,2nd and 5th weak floor,respectively.Shaking table tests simulating the minute and disastrous earthquakes are conducted,and the experiment objects are pure steel frame model with a weak floor,only added with steel brace and added with viscoelastic dampers.The results of tests and theoretical calculation indicate that the viscoelastic dampers are effective in attenuating seismic response of frame model.更多还原
