［摘要］凤凰之舟大剧院为青岛西海岸新区地标性仿生建筑。项目由上部钢结构与下部混凝土结构构成，根据造型需要，分为头部、颈部、背部、两翼、尾部等部分，内部建筑功能主要包括剧院、演艺大厅、附属车库、商业、餐饮等。针对造型及建筑功能复杂的特点，对整体结构布置、钢结构选型、传力路径进行了详细论述，并对抗连续倒塌、大跨屋面舒适度、复杂节点应力等关键问题进行了分析。结果表明，结构传力路径明确，承载力和变形满足规范要求，且留有一定的安全储备。

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
