Abstract:The No.1 building of Guiyang International Financial Center is an out-of-code high-rise building of 375-1 meters high, and it adopts structural system of concrete filled steel tubular (CFST) frame and reinforced concrete corewall with transfer story at high elevation. It is unique in the optimization of structural scheme, the limit value of axial compression ratio of corewall shear wall, the built-in steel tube of shear wall, the overall stability of the structure and the transfer story at 57th story. Through detailed structural analysis such as structural stability, transfer floor and others and structural strengthening measures, the expected C calss performance objectives could be achieved.

Keywords:out-of-code high-rise building; concrete filled steel tubular column; axial compression ratio; overall stability; transfer story at high elevation; strengthening measure
