General Information
Figure 1 shows a freestanding steel carport.
The steel structure consists mainly of five main units (blue background, 1 to 5), three front columns (installed on units 3 to 5), tie beams, purlins, and metal roofing sheets. The main units, the front columns, and the tie beams are made of circular hollow sections, while the purlins are made of rectangular hollow sections. The main unit spacing s ≅ 4.5 m, and the roof width w ≅ 6 m.
Irregular Structure
Figure 2 shows the carport.
The main units consist of back-spanned cantilever trusses that are tapered toward the free end. The cantilever trusses have two different web member arrangements (A and B). Figure 3 shows a schematic lateral view of main units 1 and 2.
The web member arrangement A has three diagonals and four verticals, while arrangement B has two diagonals, five verticals, and a single-bent longitudinal member.
Figure 4 shows main units 4 and 5.
