［摘要］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。

［关键词］斜柱外框；竖向变形；风荷载；屈曲后强度

Abstract: Foshan Fangta is a building with unique and complicated shape. The corresponding methods and design ideas to solve the main problems in the design of inclining column frame, such as scheme selection of the structural elevation, vertical deformation analysis, wind resistant design and structural component design, were introduced. Combined with the building elevation and state of force, structural elevation was determined.The wind load of the structural design can be obtained through the wind tunnel experiment. Based on the basic concept of the wind load, the input method of the wind load was determined. To make use of the strength after buckling, structural component was designed. It can be reference for similar projects.

Keywords: inclining column frame; vertical deformation; wind load; strength after buckling
