【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 style of Guangzhou Art Museum is a heroic flower in water. The composite structure system of steel tube concrete frame reinforced concrete frame and reinforced concrete core tube is adopted. Through the comparison of the schemes, the reasonable selection of the shear wall arrangement of the four core tubes can not only guarantee its function as the main anti-lateral force member, but also avoid the serious problem of the tensile force caused by the earthquake due to its large stiffness. In order to save investment, two kinds of floor system, reinforced concrete beam-slab and steel-beam-profiled steel plate composite floor system, are adopted according to the architectural modeling and the distribution of structural column net. At the same time, the long span steel beam is constructed by hinge first and then rigidly, so that both the support and the middle span can give full play to their mechanical properties. Because of the height limitation of the building, the office area above 5 stories adopts the cross-storey steel truss structure with inclined web bar. In order to fit in with the building modeling and using function, a new type of concrete filled steel tubular column with variable section and Liang Zhu joint is adopted.
