General Information

Figure 1 shows a freestanding steel carport.

The steel structure consists mainly of truss columns, back-spanned tapered trusses, knee braces, arch trusses, longitudinal trusses, purlins, sag rods, and metal roofing sheets. The truss column spacing (s) and the roof width (w) are about 5 meters. The structural members are made of hollow sections (square, rectangular, and circular), circular sections (sag rods), and trapezoidal sheets.

Figure 2 shows the carport.

There are two longitudinal truss types (1 and 2); type 1 is placed between the tapered trusses over the truss columns, while type 2 is placed over the diagonals of the arch trusses and is continuous over the entire carport length. All trusses have diagonals, except for longitudinal truss type 1. Figure 3 shows a schematic lateral view of the carport.

Figure 4 shows a schematic lateral view of the carport and an alternative variant.

The main structure of the alternative variant consists of two columns and a double-overhanging beam made of H-sections; the purlins are made of rectangular hollow sections, and the cover is made of trapezoidal sheets.
