［提要］中山古镇灯都商厦呈传统油灯状，其体形凹凸变化十分突出，结构设计具有非常大的挑战性。虽然有些方面突破了国内规范的限制，但结合工程本身的特性，结构设计上采取了多种结构体系相结合的措施，以保证体形复杂的结构在侧向刚度上的均匀性。工程利用巨型斜置钢管混凝土柱、外包钢板混凝土剪力墙、钢结构桁架、跨楼层交叉撑、加强层等组成了刚度、延性和稳定性均良好的结构体系。根据需要，结构体系沿高度进行转化，有效地解决了刚度突变、整体倾覆、中部球状悬挑等难点。经过反复的分析计算，确保了工程的安全性和经济性。

Super High-rise Structure Design of Zhongshan Guzhen Light Capital Mansion with Complicated Shape/Chen Xing, Wang Hualin, Li Na, Lin Puqiang (The Arch. Design & Research Ins. of Guangdong Province, Guangzhou 510010, China)

Abstract:The shape of Zhongshan Guzhen Light Capital Mansion looks like a traditional kerosene light, which brings much challenge to the structure design. Although some aspects of the structure design have exceeded the restrictions of domestic design standards, many structure measures are adopted to keep the uniformity of stiffness. Those measures, including huge slanting steel tube concrete column, concrete shear wall enveloped by steel plate, steel truss, across brace, strengthen story with outriggers etc., are used leading to a good structural system in stiffness, ductility and stability. Furthermore, the structural system alters at different height, thus the structural design"s difficulties in abrupt change in rigidity, overturning and overhanging in sphere shape at middle height are all solved effectively.

Keywords:complicated shape; super high-rise structure; huge slanting steel tube concretecolumn; concrete shear wall enveloped by steel plate; annular under-ground retaining wall; overturn
