佛山坊塔造型独特,体型复杂。针对斜柱外框设计中的主要问题,如立面结构方案选型、竖向变形分析、抗风设计和构件设计等,提出了相应的解决方法和设计思路。结合建筑立面和受力性能确定外框结构布置方案;通过风洞试验得到结构设计的风荷载;基于风荷载的基本概念确定风荷载的输入方法;利用屈曲后强度对构件进行设计。可供类似工程参考借鉴。
Foshan Square tower unique shape, complex body. Aiming at the main problems in the design of inclined column frame, such as the selection of vertical structure scheme, vertical deformation analysis, wind resistance design and component design, the corresponding solutions and design ideas are put forward. Combining with the building facades and the mechanical properties, the layout of the frame structure is determined; the wind load of the structure design is obtained through the wind tunnel test; the input method of the wind load is determined based on the basic concept of wind load; and the component is designed by the strength after buckling.
