核心单筒式悬挂结构中，核心筒体要承受所有的水平力及竖向力，所以核心筒体的高宽比及顶点侧向位移是这种结构的两个重要问题。文章从结构力学的基本原理出发，给出核心筒体在不同抗震烈度下的高宽比限值，并且提出了一个减少核筒顶点侧向位移的有效措施，所有这些可为建筑师和结构师提供一定的理论参考。 In the core single-tube suspension structure, the core cylinder bears all horizontal forces and vertical forces, so the aspect ratio of the core cylinder and lateral displacement of the apex are two important issues of this structure. Starting from the basic principles of structural mechanics, the paper gives the limits of aspect ratio of the core cylinder under different seismic intensity, and proposes an effective measure to reduce the lateral displacement of the apex of the nuclear cylinder, all of which can be architects and architects. Provide a certain theoretical reference.
