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,采用单一的结构体系很难满足抗侧刚度的全楼均匀性,给结构设计造成了非常大的挑战。为此,结合工程本身的外形变化特性,结构设计上采取了多种结构体系相结合的方法,根据不同平面尺寸对整体刚度的影响以及各种体系对抗侧刚度的贡献,交替采用了多种结构体系,以保证体形复杂的结构在抗侧刚度上的均匀性。工程利用巨型斜置钢管混凝土柱、内置钢管混凝土剪力墙、钢结构桁架、跨楼层交叉撑、加强层等关键技术组成了刚度、延性和稳定性均良好的结构体系,有效解决了刚度突变、整体倾覆、中部球状大悬挑等难点,对各构件交叉、楼层转换等关键点均采用了针对性措施,确保工程安全和有效实施。
Zhongshan Guzhen Dengdu commercial oil lamp was the traditional shape of the bump changes are very prominent, the use of a single structural system is difficult to meet the lateral stiffness of the whole building uniformity, to the structural design has caused a very big challenge. To this end, combined with the shape of the project itself changes in the characteristics of structural design has taken a combination of a variety of structural systems, according to different plane size of the overall stiffness of the system and the various types of lateral stiffness of the contribution to the alternative using a variety of structures System, in order to ensure the complex shape of the structure on the lateral stiffness uniformity. The key structural elements such as giant inclined concrete-filled steel tubular column, built-in concrete-filled steel tube wall, steel truss, cross-over span of floor and reinforced layer make up a structural system with good stiffness, ductility and stability, The whole overturning, the central ball over the cantilever and other difficult, cross the various components, floor conversion and other key points have adopted specific measures to ensure the safety and effective implementation of the project.
