［摘要］广州美术馆建筑造型为水中盛放的英雄花，采用钢管混凝土框架+钢筋混凝土框架-钢筋混凝土核心筒组合结构体系。通过方案对比，合理地选择4个核心筒的剪力墙布置，既保证其作为主要抗侧力构件的作用，又避免其刚度过大而导致地震作用下受拉严重的问题。为节省投资，根据建筑造型与结构柱网分布，分区域地采用了钢筋混凝土梁板和钢梁-压型钢板组合楼板两种楼盖体系，同时针对大跨度钢梁也采用了先铰接后刚接的构造措施，让钢梁支座与跨中均能充分发挥其受力性能。由于建筑层高限制，5层以上的办公区域采用局部设置斜腹杆的跨层空腹钢桁架结构。为配合建筑造型和使用功能，采用了新型的变截面钢管混凝土柱和梁柱节点。

Abstract:The architectural shape of Guangzhou Art Museum is a blossoming hero flower in water. The project adopts composite structural system of concrete-filled steel tubular frame-reinforced concrete frame-reinforced concrete corewall. Through the scheme comparison, shear wall layout with 4 corewalls was selected reasonably to ensure its function as main lateral resistant components and avoid severe tensile problem under the earthquake action due to excessively large stiffness. To save cost, two floor systems of the reinforced concrete beam slab and composite slab with steel beam and profiled steel sheet were adopted in separate areas, according to the architectural style and structural column grid distribution. At the same time, for large-span steel beams, the structural measure of "rigid connection after hinged connection" was taken to make steel beam bearing and mid-span sections give full play to its mechanical performance. Due to the building height restriction, the cross-layer vierendeel steel truss structure with partly-arranged diagonal web members was adopted in the working area in the 5th layer above. In order to meet the requirements of architectural form and use function, a new type of concrete-filled steel tubular column with variable cross-section was adopted as well as new type beam-column joint.
