［摘要］珠海歌剧院由大剧场和小剧场组成，体型均呈贝壳型。大剧场由混凝土主体及具有标志性造型的贝壳构成，主体采用框架—剪力墙结构体系。贝壳采用空间网格钢结构体系，包裹剧场核心区，为剧场提供竖向交通及配套功能用房。剧场主体高40m，贝壳高度90m。剧场结构平面不规则，且局部框支，观众厅外轮廓为空间弧形壳体，受力复杂。工程地处海岛边沿，形体较高，属于典型的风荷载控制结构。介绍了结构体系及设计难点，以及针对性的应对措施，同时采用FLUENT进行了数值风洞分析与风洞试验互相复核，给出了结构的基本静力及动力特性，并对整体稳定以及结构设计中的一些关键问题进行了深入分析。

Abstract: Zhuhai opera steel structure mainly includes large theatre and studio theatre with similar structure system. The big theatre is constructed by concrete subject and landmark plastic shell structure. The main part is made of concrete frame-shear wall structure system. The shell with space grid steel structure system, package the theatre and provide vertical transportation and supporting function room. Theater subject is 40m high, and shell is 90m high. Theater structure plane is irregular and local box branch, the audience hall outer profile for space is curved shell, and the structural force is complex. The project located in the island edge is higher, and belongs to the typical wind load control structure. It introduces the structure and design difficulties, and the taking feasible measures. By using FLUENT software, the numerical wind tunnel analysis and wind tunnel test review each other, and gives the basic the static and dynamic characteristics of structure. The problems are analysed on the overall stability and structure design.

Keywords: shell structure; inordinance; complex construction; numerical wind tunnel; opera house
