［摘要］東海商務中心一期中塔樓一為38層的超高層結(jié)構(gòu)，結(jié)構(gòu)總高度178.36m。工程采用框架核心筒結(jié)構(gòu)體系，在下部2/3高度框架柱采用鋼管混凝土疊合柱。采用PKPM和ETABS軟件進行了小震和中震的彈性計算，采用ABAQUS軟件進行了大震動力彈塑性時程分析進行驗證。針對核心筒
外圈剪力墻體平面布置不連續(xù)和底部幾層僅有局部樓板等不足進行了重點分析并有針對性地采取了加強措施。對疊合柱進行了詳細的分析，并
對節(jié)點構(gòu)造進行加強，在減小了柱截面的同時還增大了框架柱的延性和承載力。

Abstract:Shenzhen Donghai Center is a 178.36m high and 38 floors high-rise building with framed-corewall structure; Thecomposite columns(steel tube-concreted) are used from the bottom to the 25 th floor. ETABS and PKPM are used to analyze the
structure under three different grades of earthquake, and also check the structure under the high earthquake grade by using
ABAQUS. According to the plane layout discontinuousness of the shear-walls in the corewall, the intensified measures are
provided pertinently. For the composite column, detailed seismic analysis is carried out; and intensified methods for the
joints structures are provided, to not only reduce the column section but also enlarge ductibility and capacity of the framed
columns.
Keywords:high-rise building; steel tube-reinforced concrete column; dynamic elasto-plastic analysis；seismic design
