［摘要］珠海歌劇院由大劇場和小劇場組成，體型均呈貝殼型。大劇場由混凝土主體及具有標(biāo)志性造型的貝殼構(gòu)成，主體采用框架—剪力墻結(jié)構(gòu)體系。貝殼采用空間網(wǎng)格鋼結(jié)構(gòu)體系，包裹劇場核心區(qū)，為劇場提供豎向交通及配套功能用房。劇場主體高40m，貝殼高度90m。劇場結(jié)構(gòu)平面不規(guī)則，且局部框支，觀眾廳外輪廓為空間弧形殼體，受力復(fù)雜。工程地處海島邊沿，形體較高，屬于典型的風(fēng)荷載控制結(jié)構(gòu)。介紹了結(jié)構(gòu)體系及設(shè)計(jì)難點(diǎn)，以及針對(duì)性的應(yīng)對(duì)措施，同時(shí)采用FLUENT進(jìn)行了數(shù)值風(fēng)洞分析與風(fēng)洞試驗(yàn)互相復(fù)核，給出了結(jié)構(gòu)的基本靜力及動(dòng)力特性，并對(duì)整體穩(wěn)定以及結(jié)構(gòu)設(shè)計(jì)中的一些關(guān)鍵問題進(jìn)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
