In order to improve the seismic performance of the structure, this structure is composed with mega steel frame, CFT, steel frame beam / truss and reinforced concrete core wall, and formed the new hybrid structure system. The mega steel frame of the structure system is formed of two limbs at the concave plane, giant columns of the mega steel frame is formed by CFT with cross-layer column bracing at the end of two limbs, giant beams of the mega steel frame is formed by cross-layer connected truss between two limbs. The structure characteristics, overall calculation results, the main design problems and solutions were described systematically.Keywords: super high-rise structure; concave plane; mega frame; hybrid structure作者簡介：李霆，教授級高級工程師，Email: lting@vip.sina.com.參考文獻(xiàn)［1］ 安徽高速地產(chǎn)·濱湖時代廣場C-01地C1棟超限高層建筑工程抗震設(shè)防可行性論證報告［R］.武漢：中南建筑設(shè)計院股份有限公司，2012.［2］ 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.［3］ TERREY P J, BRADFORD M A, GILBERT R I.
