General Information

Figure 1 shows a steel canopy roof.

Figure 2 shows the roof structure viewed from below.

The steel structure consists mainly of transverse and longitudinal beams, purlins, diagonal roof braces, four suspension rods with a square hollow cross-section, and metal roofing sheets. Figure 3 shows the canopy roof viewed from the side.

The length l ≅ 4.5 m, and the width b ≅ 4 m. The transverse back beam and the suspension rods are connected to the reinforced concrete structure of the building. The suspension rods have two different inclination angles (α1 and α2) and converge toward the external longitudinal beams. Figure 4 shows a schematic partial three-dimensional view of the structure.

Figure 5 shows a variant with two suspension rods.

Each suspension rod is made of a single steel wire rope. The remaining roof structure equals the used variant.
