防城港文化艺术中心项目为造型新颖的贝壳形仿生建筑,空间关系复杂,建筑物平面为不规则的贝壳状扇形,最长处125m,最宽处115m。主体结构为现浇钢筋混凝土框架-剪力墙结构,屋面为空间钢网壳结构,结构设计具有一定的难度。对结构设计中所遇到的复杂屋盖结构的建模、抗风设计、抗震设计、基础选型、防腐蚀措施等关键问题的处理思路和方法进行了介绍,可为类似项目的结构设计提供一定的参考。
Fangchenggang Cultural and Art Center project is a novel shell-shaped bionic building with complicated spatial relationship. The building plane is an irregular shell-shaped fan with the longest 125m and the widest 115m. The main structure is cast-in-place reinforced concrete frame-shear wall structure, the roof is space steel reticulated shell structure, the structural design has a certain degree of difficulty. This paper introduces the treatment ideas and methods of the key problems such as the modeling of the complex roof structure, the wind resistance design, the seismic design, the foundation selection and the anti-corrosion measures encountered in the structural design, which can provide the structural design for similar projects Certain reference.
