［摘要］国家电网公司上海世博会企业馆抗侧力结构布置结合建筑外立面斜交叉纹理采用联合空间结构体系。其中楼、屋面以及正交斜放柱网共同构成了一个空间结构，魔盒（CUBE）六面体采用双向双层正交空腹平面桁架组成又一个空间结构。魔盒六面体通过四根巨型钢柱及牛腿挂在正交斜放柱网主体结构上，形成了联合空间结构体系。支承魔盒的四根巨型钢柱为“悬浮”在建筑中心位置的魔盒提供了有效的支承。正交斜放柱网与魔盒六面体组成的联合空间结构实现了建筑与结构统一的外立面构想。该建筑的地下部分是世博会的电力调配系统，结构采用梁柱转换方式，满足了上下结构不同的功能要求。

Abstract: The anti-side force structure system of State Grid Corporation in Shanghai World Expo Enterprise Pavilion is combined spatial structural system, combining the diagonal cross texture on the facade of the building. The floor, the roof and the orthogonal diagonal column grid together form a spatial structure, and the Magic Box (CUBE) hexahedron is bi-directional double-layer orthogonal vierendeel planar truss, forming another spatial structure. The Magic Box (CUBE) hexahedron, supported by four giant steel columns and corbels, is hanging on the main structure (the orthogonal diagonal column grid), forming the combined spatial structure system. The four giant steel columns provide effective support for the suspended Magic Box in the center of the building. The combined spatial structure system formed by the orthogonal diagonal column grid and the Magic Box (CUBE) hexahedron makes the architecture and structure achieve unity on the idea of building facade. The basement of this building is used to protect the power provision system of the Expo, it adopts column-beam conversion system, meeting different functional requirments in the upper and lower parts of the building.

Keywords: orthogonal diagonal column grid; combined spatial structure system; dynamic characteristics; stability; comfort; finite element analysis of node
