世博会国家电网企业馆采用周边具有正交斜放支承柱的网格结构,外墙角不设角柱,楼屋盖采用正交正放的平面桁架系.它们共同组成三个盒型空间抗侧力体系.主体结构中部开口为空间六面体魔盒,每个面均采用双层双向正交空腹平面桁架,在魔盒的每个棱边布置支撑对角部进行加强.建筑效果和结构设计达到和谐统一.本文对该结构的体系构成、计算分析内容和结果进行简要介绍.结构计算分析内容包括荷载分析、地震作用分析、温度作用分析、稳定性分析、节点分析、楼盖舒适度分析和施工模拟加载分析.针对魔盒内人行天桥水平张弦梁的设计,本文推导了确定竖杆下节点坐标的手算方法.
The State Grid Enterprise Pavilion of World Expo adopts a grid structure with orthogonally slanting support columns in the periphery, with no corner columns in the corner walls and flat truss systems with orthogonal orthogonados in the roof, which together form three box-type lateral resistance systems The main structure of the central opening of the hexahedral hexahedron box, each side are using two-way two-way orthogonal flat-shaped truss truss on each edge of the magic box arranged to support the diagonal to strengthen the building effect and structural design to achieve harmony and unity. In this paper, the structure, calculation and analysis of the structure and the results are briefly introduced.The structural calculation and analysis include load analysis, seismic effect analysis, temperature effect analysis, stability analysis, node analysis, floor comfort analysis and construction simulation loading analysis Aiming at the design of the horizontal beam of the footbridge in the box, this paper deduces the method of determining the coordinates of the node under the vertical bar.
