［摘要］鳳凰之舟大劇院為青島西海岸新區(qū)地標性仿生建筑。項目由上部鋼結(jié)構(gòu)與下部混凝土結(jié)構(gòu)構(gòu)成，根據(jù)造型需要，分為頭部、頸部、背部、兩翼、尾部等部分，內(nèi)部建筑功能主要包括劇院、演藝大廳、附屬車庫、商業(yè)、餐飲等。針對造型及建筑功能復(fù)雜的特點，對整體結(jié)構(gòu)布置、鋼結(jié)構(gòu)選型、傳力路徑進行了詳細論述，并對抗連續(xù)倒塌、大跨屋面舒適度、復(fù)雜節(jié)點應(yīng)力等關(guān)鍵問題進行了分析。結(jié)果表明，結(jié)構(gòu)傳力路徑明確，承載力和變形滿足規(guī)范要求，且留有一定的安全儲備。

Abstract: Phoenix Boat Grand Theater is a bionic landmark building in Qingdao West Coast New District. The project is composed of upper steel structure and lower concrete structure. According to the modeling needs, it is split into head, neck, back, wings, tail and other parts. The internal architectural functions mainly include theater, performance hall, auxiliary garage, commerce, catering, etc. According to the characteristics of complex modeling and building functions, the overall structure layout, steel structure selection, and force transmission paths were discussed in detail. Key issues such as resistance to progressive collapse, comfortableness for large-span roof, and stress on complex joints have been analyzed. The results show that the force transmission path of the structure is evident, the bearing capacity and deformation meet the requirements of the code, and there is a certain safety reserve.
Keywords:Phoenix Boat Grand Theater； bionic building； steel structure selection； force transmission path； resistance to progressive collapse； comfortableness analysis； joint analysis
