摘　　要：广东省三馆合一项目外形宛如一艘满载艺术宝盒的巨轮扬帆起航。新颖的建筑造型使结构具有不对称复杂连体、高大空间斜幕墙、大跨度转换等结构设计难点,结构采用钢桁架与钢筋混凝土框架-剪力墙结构相结合的结构体系。分析了地震作用下连体结构连接体变形协调和塔楼间内力分配特点,并提出一系列有针对性的设计措施;结合高大空间斜幕墙的特点,利用幕墙立柱和横梁共同组成双向受力刚性结构体系,提出H型钢梁空间斜交网格幕墙结构体系,分析了幕墙结构对主体结构侧向刚度及竖向构件内力的影响,并提出设计对策;针对由于道路隧道下穿地下一层造成托换结构跨度大、托换层数多的特点,采用合理的结构形式,并提出合理的抗震性能要求及节点构造形式。The Three Museums in One project in Guangdong Province is shaped like a giant ship full of art treasure boxes.The novel architectural form presents structural design difficulties such as asymmetric and complex connections,high spatial inclined curtain walls,and large-span conversions.The structure adopts the structural system combining steel trusses and reinforced concrete frame shear-wall structures.The characteristics of deformation coordination and internal force distribution between towers of connected structures under earthquake were analyzed,and a series of targeted design measures were put forward.Based on the characteristics of high spatial inclined curtain walls,a type of H-shaped steel beam spatial oblique grid curtain wall structure system was proposed by combining curtain wall columns and beams to form a bi-directional rigid structural system.The influence of curtain wall structure on the lateral stiffness of the main structure and the internal force of vertical components was analyzed,and design countermeasures were proposed.In view of the characteristics of large-span and many underpinning layers of the underpinning structure caused by the road tunnel passing through the underground layer,a reasonable structural form was adopted,and reasonable seismic performance requirements and joint structure forms were put forward.
