［摘要］國家電網(wǎng)公司上海世博會企業(yè)館抗側(cè)力結(jié)構(gòu)布置結(jié)合建筑外立面斜交叉紋理采用聯(lián)合空間結(jié)構(gòu)體系。其中樓、屋面以及正交斜放柱網(wǎng)共同構(gòu)成了一個空間結(jié)構(gòu)，魔盒（CUBE）六面體采用雙向雙層正交空腹平面桁架組成又一個空間結(jié)構(gòu)。魔盒六面體通過四根巨型鋼柱及牛腿掛在正交斜放柱網(wǎng)主體結(jié)構(gòu)上，形成了聯(lián)合空間結(jié)構(gòu)體系。支承魔盒的四根巨型鋼柱為“懸浮”在建筑中心位置的魔盒提供了有效的支承。正交斜放柱網(wǎng)與魔盒六面體組成的聯(lián)合空間結(jié)構(gòu)實(shí)現(xiàn)了建筑與結(jié)構(gòu)統(tǒng)一的外立面構(gòu)想。該建筑的地下部分是世博會的電力調(diào)配系統(tǒng)，結(jié)構(gòu)采用梁柱轉(zhuǎn)換方式，滿足了上下結(jié)構(gòu)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
