摘要
首先介绍了Y型偏心支撑钢框架的优缺点和粘弹性阻尼减震结构的基本原理,然后基于动力弹塑性时程分析方法,比较分析了以不同方式设置粘弹性阻尼器对结构动力性能的影响及相应的位移和加速度减震效果。
In this paper, firstly, the advantages and disadvantages of Y-EBSF and the basic principles of structures with viscoelastic dampers were discussed. And then, the influence of Y-Eccentrically Braced Steel Frames dynamic performance of different cases of mounting viscoelastic dampers and the correspondent anti-vibration effect of displacement and acceleration were compared based on the non-linear time-history analysis.
