[摘要] 防城港文化艺术中心项目为造型新颖的贝壳形仿生建筑，空问关系复杂，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一剪力墙结构，屋面为空问钢网壳结构，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。

Abstract: Fangchenggang Culture&Art Center is a building that has a large span roof with complex bionic shape, which brings challenge for structural design. With an irregular scallop-shaped plan, this building is 125m long and 115m wide. The main structural system is concrete frame with shear walls, while the steel roofis a latticed shell structure. Key issues in structural design such as modeling of the complicated roof, wind-resistant and seismic design, selection of foundation, and anti-corrosion design were discussed. This project can be a good reference for the design of similar buildings.
Keywords: large span space structure; latticed shell; buckling analysis; wind-resistant design; time history analysis; anti-corrosion
