粘滞阻尼器在某框架结构中的减震性能分析

Analysis of Damping Performance of Viscous Dampers in Frame Structures

文中对某框架结构采用粘滞阻尼器进行耗能减震性能分析,在多遇地震作用下粘滞阻尼器的减震率最大达到28.8%,在罕遇地震作用下粘滞阻尼器的减震率最大达到11.4%。结果表明:设置粘滞阻尼器使得框架结构的抗震能力大大加强,粘滞阻尼器在框架结构中表现出良好的耗能性能,可大量耗散地震能量,减少结构损伤,减震效果明显。

The performance of a frame structure with viscous dampers is analyzed.The damping rate of viscous dampers is 28.8%under frequent earthquakes and 11.4%under rare earthquakes.The results show that the seismic ability of the frame structure is greatly enhanced by the installation of sticky paper dampers.The viscous dampers show good energy dissipation performance in the frame structure,and can dissipate a large amount of seismic energy to reduce structural damage,and the damping effect is obvious.
