摘要
文中介绍了2010年上海世博会中国馆国家馆的总体概况———4个筒体从地区馆升起,空中连成整体作为展厅,层叠出挑,呈倒四棱台斗冠状.阐述了国家馆的一些结构设计特点———依建筑外形设置的斜柱,为楼盖大梁提供竖向支承,满足了展厅内没有柱子的大空间使用功能要求,通过加强斜柱根部楼层的连梁和楼盖刚度,使33.3 m标高楼盖自相平衡地受压而不是剪力墙受剪来承担更多的斜柱水平分力.此外,还介绍了41.4、49.5、60.3和69.9 m标高楼盖的结构布置及3根斜柱交汇处的节点做法、组合梁的起拱原则、内力较大处梁的做法、抗震设计等.
In this paper,the general situation of China National Pavilion at the Expo 2010 Shanghai China is introduced,the four tubes rising from the Regional Pavilion and connecting in the air being the exhibition hall with spreading layer upon layer,just like an inverse quadrangular frustum pyramid crown.Moreover,some characteristics of the structure design of the National Pavilion are expounded,which includes that so as to columns set based on the shape of the building vertically support the girders of floor inclined satisfy the demand of the big space service function without column within the exhibition hall,and by strengthening the stiffnesses of the coupling beam and the floor at 33.3 m elevation,the press of the floor is used to resist more horizontal component force from the inclined columns by means of self equilibrium rather than the shear of shear wall.Besides,the authors also introduce the structure layout at the elevations of 41.4,49.5,60.3 and 69.9 m,the joint configuration of connecting three inclined columns,the camber principle of composite beam,the measures in dealing with the girder with large internal force,seismic design,etc.
