［摘要］贵阳国际金融中心1号楼为高度375-1m的超限高层建筑，采用带高位转换的钢管混凝土柱框架-钢筋混凝土核心筒结构体系。在结构方案优选、核心筒剪力墙的轴压比限值、剪力墙内置钢管、结构整体稳定性、57层高位转换等方面均具有独到之处。通过结构稳定、转换层等一系列详细分析以及构造加强措施，可达到预期的C级性能目标要求。

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.
