Two shear wall cores are put at the two sides of the building layout, and four single-span frames are put in the middle. In view of the particularity of the super high-rise building with single-span frame, two structural schemes were compared from the mechanical behaviour and economical efficiency, and the composite structure was chosen for the direction of structure design. The frame column, floor steel beam and enhance stories connect truss were redesigned to make a further development of the structural optimizing design. These effective measures make the structure more efficiency in the mechanical behaviour and economy, which can provide reference for the similar project.Keywords:super high-rise building; single-span frame; structural scheme selection; structural optimization作者簡介：黃忠海，碩士，工程師，Email:huangzhonghai19@163.com。參考文獻［1］CECS230:2008高層建筑鋼混凝土混合結構設計規(guī)程［S］. 北京：中國計劃出版社，2008.［2］JGJ3—2002高層建筑混凝土結構技術規(guī)程［S］. 北京：中國建筑工業(yè)出版社，2002.［3］黃忠海，廖耘，李志山，等. 珠江新城J2-5地塊框架-核心筒超高層結構的罕遇地震彈塑性時程分析［J］. 結構工程師，2009，25（2）：91-97.
