摘　　要： 在总结深圳新世纪广场、鹏运广场、中航广场等超高层结构设计的基础上,对超高层建筑结构加强层伸臂的合理计算模型进行分析探讨。对带有结构加强层的超高层建筑结构水平位移特征曲线,主体结构的内力规律特征进行分析,并利用材料力学基本概念对其产生机理进行论述。根据结构加强层范围内主体结构的力学特性,提出加强层范围内主体结构为“大核心区”的概念。对“大核心区”的结构设计和构造措施提出见解。 On the summarized basis of the structural designs of New Century Square,PengYun Square, ZhongHang Square and other high-rise buildings i n Shenzhen, this paper discusses and analyzes the rational calculating model of high-rise buildings with outer-arm in the reinforced layer, the characteristic c urve of horizontal displacements for a high-rise buildings with the structural r einforced layer, and the internal force rules and characters of the tube structu re. And its mechanism is also discussed through basic concepts of material mecha nics. The concept that 'large core zone' is the tube sturcture within the are a of reinforced layer has been Presented on the basis of the mechanical characte ristics. In the end this paper gives opinions on the structural design and const ructive methods of zone.

关 键 词： 结构加强层主体结构 计算模型 大核心区
