［摘要］桂林两江国际机场T2航站楼屋盖采用空间实腹拱支撑+单层壳体钢结构体系，中心区支撑拱最大跨度120m，为双曲实腹拱，屋盖壳体为双曲面壳体，节点连接为刚接，节点形式复杂，通过简化、标准化节点的构造，采用以节点连接方式指导杆件定位的原则，再进行几种节点连接方式的应力分析比较，确定了合理的节点连接形式，既便于制作安装，又保证了节点受力性能，实现了建筑效果。

Abstract:Guilin Liangjiang International Airport T2 terminal building adopts the spatial solid web arch support+single-layer shell steel structural system. The maximum span of the supporting arch in the central area is 120m. It is a hyperbolic solid web arch. The roof shell is a hyperbolic shell with rigid joints. The joints are complex. By simplifying and standarlizing the joints construction, the method of joint connecting was adopted as the principle to guide the component positioning, and then stress analysis and comparison of several joint modes were conducted to determine a reasonable joint form. This was convenient for fabrication and installation, and the mechanical performance of the joint was guaranteed, and the architectural effect was realized.

Keywords:Guilin Liangjiang International Airport; arch shell structure; large span; terminal building; steel structure
