附加粘弹性阻尼墙结构设计应用

Design Apllication of Stuctures with the Viscoelastic Damping Walls

利用结构设计软件Etabs对某部委全钢结构的办公大楼进行分析。原结构采用框架偏心支撑体系,有控结构则以粘弹性阻尼墙取代部分支撑,对2种结构体系在各种地震加速度峰值作用下的各项性能指标进行分析比较,得出结论:粘弹性阻尼墙可以有效减小结构的地震反应,提高了结构的抗震性能,且满足规范的各项要求。

Carried on the analysis of some all steel structure office building by using structural design software Etabs.The original structure uses frame bias supporting system,and some part of supporting is substituted by the viscoelastic damping wall.carries on the analysis Compared the performances of two kinds of structure systems under different kinds of earthquake acceleration peak values,draws the conclusion： The viscoelastic damping wall can effectively reduce the structure＇s earthquake response,enhanced the structure＇s earthquake resistance performance,and satisfies the related requests of standards.
