某冰雪设施场馆结构设计

Structural design of an ice and snow facility venue

本项目为新建冰雪设施场馆,分为A、B、C三个单体,对同类型冰雪设施场馆具有一定的参考价值。A馆首层地面搁置大荷载设备,可通过对首层进行地基处理的方式,解决承载力和变形问题。结合建筑功能及荷载特点,A馆采用双层网壳结构,在中部设置4个支撑点,有效减小屋盖跨度,提高屋盖的承载能力。B、C馆采用单层网壳+开花柱的结构形式,网壳采用箱形截面,开花柱采用圆管,分叉位置刚接,与网壳连接部位采用销轴连接,为增加单层网壳的自平衡能力,对周圈环梁截面予以加强,增强了边界约束。

This project is a newly built ice and snow facility venue,which is divided into three units:A,B and C,which has certain reference value for the same type of ice and snow facility venue.The ground of Hall A is shelved with large load equipment,and the bearing capacity and deformation problems can be solved by treating the foundation of the first floor.Combined with the building function and load characteristics,Hall A adopts a double-layer grid shell structure,and four support points are set in the middle to effectively reduce the span of the hut cover and improve the bearing capacity of the roof.Hall B and C adopt the structural form of single-layer grid shell+flowering column,the grid shell adopts box-type section,the flowering column adopts round tube,the bifurcation position is just connected,and the connection part of the grid shell adopts pin shaft connection,in order to increase the self-balancing ability of the single-layer grid shell,the ring beam section is strengthened and the boundary constraint is enhanced.
