Its dimensions are approximately 640 m in width and 324 m in length, with a structural height varying between 3.0 m and 4.5 m. The shape of the roof is relatively flat with a slight curvature in the area a

The primary structure of the terminal consists of truss girders that span rectangular between the supp
8、orting columns (Figure F-5). In a regular field, the distance between two columns is 36 m. The truss girders are fixed to the columns and build a stiff frame, in order to brace the roof structure. ? Figure F-5? ? 36 ? ? Figure F-5: Primary Structure ? F-5?

The secondary str
10、ucture itself is divided into primary and secondary elements, where the primary elements form a spatial framework (Figure F-6). ?Figure F-6? Figure F-6: Primary Members of Secondary Roof Structure ? F-6? The secondary elements in between the rhombi consist of purlin crosses (Figure F-7), which are p
11、inned to the primary elements. In a purlin cross, two of the four purlin connections have axial hinges as well, so that the purlin crosses will transfer loads mainly by bending and tension. ?Figure F-7? ? 36 m 36 m 9 m 6 m Shenzhen International Airport Terminal 3 Roof Structure Structural Narrative
