摘　　要：为达到建筑效果,广东省博物馆新馆结构上利用建筑的竖向交通区域设置内置钢管混凝土剪力墙作为结构的抗侧构件和竖向承重构件,在剪力墙顶部设置大跨度的悬臂钢桁架。通过在桁架上设置竖向吊杆悬吊外围展厅和中庭回廊,并在外围设置空间构架作为建筑外墙的主支撑骨架。为了尽可能使结构布置简洁、受力合理、施工方便,设计时对结构布置不断进行优化,确保在有效的结构布置前提下进行结构设计。In order to reflect the intention of the architectural scheme, the lateral force resisting system and vertical loads supporting system are established in the vertical transportation region with shear wall tubes embedded with CFST columns, then the tubes are crowned with the long span overhang steel trusses, the vertical bars are suspended from the trusses to support the exhibition hall＇s floors and the quadrangle winding corridors, space frames are set up on the perimeter supporting the walls on the elevations. The architecture surface effect realizes with crown the bracket steel truss, winding corridor and constructs the periphery space frame skeleton on the outer wall. Optimization design is done to achieve simpler structural arrangement, more reasonable internal force distribution and greater convenience in construction.
