摘要
阐述了金属剪切型阻尼器的工作机理及连接方式,并对6层混凝土框架结构增设墙式连接的金属剪切型阻尼器,设定减震目标,通过ETABS软件进行时程分析,研究金属剪切型阻尼器在不同地震作用下的减震性能。结果表明,在多遇地震和罕遇地震作用下,金属剪切型阻尼器的减震率均高于减震目标,阻尼器在结构中充分耗能,减震效果明显,可为工程减震设计设计师提供借鉴。
This article elaborated on the working mechanism and connection method of metal shear dampers,and added wall connected metal shear dampers to a 6-story concrete frame structure.The seismic reduction target was set,and time history analysis was conducted using ETABS software to study its seismic performance under different earthquake conditions.The results indicate that the damping rate of metal shear dampers is higher than the damping target under both frequent and rare earthquake conditions.The dampers fully dissipate energy in the structure and have a significant damping effect.Provide reference for engineering shock absorption design designers.
