Abstract: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 000m2. 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.

Keywords:Guangzhou New Baiyun International Airport；terminal；steel roof；ribbed space truss；　free-form surface
