［摘要］南宁华润大厦A座是由底部办公、顶部酒店组成的445m超高层建筑。因其建筑功能及立面要求，形体沿高度由南向北逐渐收缩，核心筒顶部单边收进，这种特殊的体型给结构设计带来很多复杂的难题。首先对核心筒偏心收进引起的基础不均匀沉降进行研究，然后对斜墙部位的受力特性和结构加强措施进行分析和阐述，最后就竖向偏心荷载下结构的水平变形进行解读，并提出结构解决方案。

Abstract:Nanning China Resources Tower A is a 445m high super tall building composed of offices at the bottom and hotels at the top. Because of its architectural function and facade requirements, the shape gradually shrinks from south to north along the height, and the top of the corewall is indented unilaterally. This special shape brought many complex problems to the structural design. Firstly, the uneven foundation settlement caused by the corewall eccentric indention was studied, and then the mechanical characteristics of the oblique shear wall and the structural strengthening measures were analyzed and elaborated. Finally, the horizontal displacement of the structure under the vertical eccentric load was interpreted, and the structural solutions were proposed.

Keywords:super tall building; eccentric indention; horizontal displacement; oblique shear wall
