西班牙国家馆是2010年上海世博会临时场馆之一。建筑包括多功能厅、展厅、餐厅、报告厅、SEEI办公和辅助用房。建筑造型借鉴了中国与西班牙共有的传统工艺——藤编,在该建筑立面呈现出柳条编织的篮子形状,体现了东方与西方、中国与西班牙相连的意境。西班牙馆建筑表现效果要求高,形态复杂,存在多处水平和竖向的空间扭转曲面,对结构设计提出了极大的挑战。从结构选型入手,提出几种不同的立面杆系布置方案,以结构性能参数为量化指标选取最优方案。在优选方案的基础上,对西班牙馆的结构体系、抗风抗震以及重要节点进行了分析与设计。分析表明:立面采用杆件正交布置的双层空间框架结构具有较好的受力、变形和抗震性能,相贯节点安全可靠。相关结构杆系选型和分析内容对类似复杂建筑形态结构设计有较好的参考价值。
Spain Pavilion is one of the temporary venues for the 2010 Shanghai World Expo. The building includes multi-purpose hall, exhibition hall, restaurant, lecture hall, SEEI office and auxiliary room. Building modeling draws on the common craftsmanship of China and Spain - rattan, the shape of a wicker basket in the building facade, reflecting the artistic conception of the East and the West, China and Spain. Spanish Pavilion architectural performance demanding, complex shape, there are many horizontal and vertical space torsion surface, the structural design presents a great challenge. Starting from the structure selection, several different layout schemes of the facade pole system are proposed, and the optimal scheme is selected based on the structural performance parameters as the quantitative index. On the basis of the optimal scheme, the structural system of the Spanish pavilion, wind and earthquake resistance and important nodes are analyzed and designed. The analysis shows that the double-deck space frame with orthogonal arrangement of the bars has better stress, deformation and seismic performance, and the joints are safe and reliable. Related structural rod system selection and analysis of the contents of similar complex architectural morphology and structural design has a good reference value.
