The analysis method and process of super high-rise structures with metal energy dissipation devices were illustrated, in order to fully understand the seismic analysis procedures of energy dissipation structure and avoid the overrated effective total damping ratio. Taking tower C of Tianjin International Trade Center as an example, the feasibility and economics of super high-rise structures with metal dissipation devices were introduced.Keywords: super high-rise structure; energy dissipation structure; metal energy dissipation device; equivalent linear analysis method作者简介:尤旭升,一级注册结构工程师, Email:you.xusheng@capitaland.com.cn。参考文献[1]高承勇, 张家华. 建筑结构中阻尼器消能减震设计关键技术的探讨[J]. 建筑结构,2009, 39(5):18-22.[2]GB 50011—2010建筑抗震设计规范[S]. 北京:中国建筑工业出版社,2010.[3]JGJ 297—2013建筑消能减震技术规程[S].[4]JGJ 3—2010高层建筑混凝土结构技术规程[S]. 北京:中国建筑工业出版社,2011.[5]陈清祥,潘琪.静力分析方法在消能减震结构分析中的应用[J].防灾减灾工程学报,2012,32(4):436-443.
