General Information

Figure 1 shows a freestanding steel carport.

Structural Concept

Figure 2 shows the carport.

The steel structure consists mainly of four columns, four trusses, knee braces, beams, purlins, and metal roofing sheets. The span s ≅ 3 m, and the span l ≅ 8 m. The front and the back truss are single-side overhanging, as shown in figure 3.

The overhanging length a ≅ 1.5 m. The front truss does not have diagonals in the overhanging region; the back truss does not have diagonals over the entire length. The front and the back truss are knee braced in the overhanging region as well as mid-span connected. Figure 4 shows the front to back truss mid-span connection.

The mid-span connection consists of two square hollow profiles that are placed one over the other and joined by welding. Figure 5 shows a schematic partial three-dimensional view of the carport structure.

Figure 6 shows a different variant.

The steel structure consists mainly of four columns, beams, purlins, and metal roofing sheets. Variant A and the used variant have the same external geometry and columns layout.
