衛(wèi)文，陳星（廣東省建筑設(shè)計研究院， 廣州 510010）［摘要］為了保證結(jié)構(gòu)加強層設(shè)置的合理與有效，通過工程實例介紹了在超高層建筑中合理設(shè)置加強層的思路和方法，對多種可能性做計算分析、判斷，最終確定加強層的數(shù)量和位置。針對超高層建筑進行了加強層設(shè)置屈曲約束支撐的對比分析。分析結(jié)果顯示，對于高烈度區(qū)的罕遇地震，屈曲約束支撐具有一定的滯回性能，可以減小結(jié)構(gòu)地震反應(yīng)，但減小效果不大。［關(guān)鍵詞］超高層建筑； 加強層； 屈曲約束支撐中圖分類號：TU398.7 文獻標(biāo)識碼：A 文章編號：1002-848X(2013)14-0048-05Analysis on strengthened story of a super high-rise buildingWei Wen, Chen Xing(The Architectural Design & Research Institute of Guangdong Province, Guangzhou 510010, China)Abstract: For the purpose of insuring the rationality and effectiveness of setting strengthened story, the thinking and method to set the stiffening layer in super high-rise building were introduced with an actual project. The calculation and analyses were needed to determine the amount and the location of the strengthened story. The comparative analysis of using buckling restrained brace in strengthened story of super high-rise building was carried out. And the results of the analysis show that when using the buckling restrained brace in rarely occurred earthquake of highly seismic region, there is some hysteretic behavior in it, and can minimize the earthquake response but is not so effective.Keywords: super high-rise building; strengthened story; buckling restrained brace作者簡介：衛(wèi)文，碩士，高級工程師，Email: cicely111@126.com。參考文獻［1］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.［2］GB 50016—2012建筑設(shè)計防火規(guī)范［S］.送審稿.
