摘要
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。
To meet the requirements of architectural design, wave-like hyperbolic steel roof and single-layer quadrilateral oblique crossing grid are used in the structural system of Suzhongjiangdu Airport Terminal. The steel roof, oblique crossing grid and lateral force-resisting members were analyzed to determine the reasonable structural system. Dynamic and static characteristics of the steel roof were researched and the results have proved that the structure has reliable mechanical performances. Aesthetic requirements of exposed structure were considered when selecting the section of steel roof members and connections. Architectural modeling and design concept are reflected well in the structure.
