摘　　要：广州新白云国际机场T2航站楼为国内大型枢纽机场,国家重点工程。航站楼钢屋盖面积约为25万m2,下部结构为钢筋混凝土框架结构,上部屋盖结构体系为网架结构,主楼采用加肋网架并局部采用抽空处理。航站楼结构超长,平立面布置复杂,屋盖形状为自由曲面,针对结构设计中遇到的如柱顶支座节点、与钢管混凝土柱连接的双梁节点等关键技术问题,采取了相应的技术措施。分析结果表明,结构具有可靠的受力性能。T2 terminal of Guangzhou New Baiyun International Airport is one of large scale transports and important projects in China. The area of the whole steel roof of the terminal is about 250 000m^2. Steel concrete frame structure is adopted as lower-part structure. The upper steel roof adopts space truss structure. The ribbed space truss is used in the main building of terminal with partial member removal. The terminal is super long and has complex plane and elevation, the roof is free-form surface. According to many key design problems, such as support joints on the top of the column, double beam joints connected with concrete-filled steel tubular columns, corresponding technical measures were adopted. Analysis results show that the structure has reliable performances.
