(1.Shanghai Institute of Architectural Design and Research Co.Lad.Shanghai 200041 China; 2.Ningbo Eastern New City Intestment and Development Co.Lid.Ningbo Zhejiang 315040 China) Abstract:The structural system of the steel tubular concrete column and steel frame beams-reinforced concrete core tube is adopted in Ningbo Zhongyin Building.The project has key design problems of super-long basement torsional shaped tower building core tube transfers and large scale steel awnings. This paper introduced the design of foundation and underground structure and then emphatically described the key problem of structural design and calculation analysis of Ningbo Zhongyin Building such as seismic shearing force ratio of frame lateral storey stiffness shear resistance capacity of storey analysis of elastic time-history and core tube transfer block.Finally the strengthening measures for seismic design are determined. Key words:tall buildings;structural design;core tube;transfer storey;inclined columns;tube ...
