中文摘要：

根据新型粘弹性-摩擦阻尼器（FVD）的耗能特点和底部薄弱层结构动力特性，提出通过对底部薄弱层结构设置FVD，达到对底部薄弱层结构抗震加固的目的。为了验证该方法的抗震控制效果，设计制作了带有底层薄弱层的五层钢框架模型，在其底层薄弱层设置FVD支撑，进行了罕遇地震和多遇地震下的振动台试验。试验结果表明，FVD支撑能够有效地控制结构的地震反应。

英文摘要：

To overcome some problems in the aseismatic buildings which have weak layers at the bottom, the friction-viscoelastic damper is equipped with the build, based on the energy consumption characteristic of new FVD. A model of five-storey steel frame which has weak layers at the bottom is designed and equipped with the FVD at the weak layers. 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 FVD. The results of the tests indicate that the FVDs are effective in attenuating seismic response of the frame model.
