Abstract:Dacheng Financial Business Center in Kunming has  A tower with height of 199-7m and B tower with height of 130-8m. Both towers adopt the innovative structural system of steel frame (steel tube filled with concrete column) -steel frame eccentric braced inner tube- composite floor. On the basis of the comparison of  four  structural schemes, the structural scheme was selected to not only meet the building service function, but also to achieve the economy and construction convenience. Appropriate performance objectives were put forward in view of the project′s out-of-code situation and objectives were analyzed and demonstrated one by one, and the corresponding strengthening measures were taken. According to the characteristics of the innovation structural system, the whole stability analysis was carried out specifically. The results show that the main structure has superior seismic performance.

Keywords:super high-rise building； innovative structural system； inclined column； steel frame； steel eccentric braced inner tube
