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作者簡介:尤旭升,一級注冊結(jié)構(gòu)工程師, Email:you.xusheng@capitaland.com.cn。參考文獻[1]高承勇, 張家華. 建筑結(jié)構(gòu)中阻尼器消能減震設(shè)計關(guān)鍵技術(shù)的探討[J]. 建筑結(jié)構(gòu),2009, 39(5):18-22.[2]GB 50011—2010建筑抗震設(shè)計規(guī)范[S]. 北京:中國建筑工業(yè)出版社,2010.[3]JGJ 297—2013建筑消能減震技術(shù)規(guī)程[S].[4]JGJ 3—2010高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程[S]. 北京:中國建筑工業(yè)出版社,2011.[5]陳清祥,潘琪.靜力分析方法在消能減震結(jié)構(gòu)分析中的應(yīng)用[J].防災(zāi)減災(zāi)工程學(xué)報,2012,32(4):436-443.
