苏中江都机场航站楼钢屋盖为波浪式双曲屋面,屋盖结构结合建筑造型要求,采用了多榀钢屋架+单层四边形斜交网格的结构体系。针对钢屋架、斜交网格等不同方案以及抗侧力构件的分析、比较,确定了合理的结构方案。钢屋盖的动力特性和静力分析表明结构具有可靠的受力性能。选用屋盖构件截面、连接节点时充分考虑了外露结构的美观要求,结构较好地体现了建筑形态和设计理念。
The steel roof of the terminal of Jiangzhong Airport in Jiangsu is a wave-shaped hyperbolic roof. The structure of the roof is combined with the architectural modeling requirements. The structural system of the multi-span steel roof truss + single-layer quadrilateral skew grid is adopted. Aiming at the different schemes such as steel truss girder, skew grid and the analysis and comparison of the anti-lateral force members, a reasonable structure scheme has been determined. The dynamic characteristics and static analysis of the steel roof indicate that the structure has reliable mechanical properties. The section of the roof member is selected, the appearance requirements of the exposed structure are fully taken into account when connecting the nodes, and the structure better reflects the architectural form and the design concept.
