General Information
Figure 1 shows a freestanding steel carport.
The steel structure consists mainly of two truss columns, four cantilever units (marked by the numbers), a tie truss without diagonals, two roof cross braces, purlins, and metal roofing sheets. The truss columns and the cross braces are made of circular hollow sections, while the cantilever units and the purlins are made of rectangular hollow sections. The carport length l ≅ 7 m, and the width w ≅ 5 m.
Structural Concept
Figure 2 shows a schematic carport layout.
The external cantilever units (1 and 4) are front and back braced and are connected to the truss columns, while the internal cantilevrer units (2 and 3) are front braced and connected to the tie truss. The cross braces are connected to the truss columns and to cantilever units 2 and 3. Figure 3 shows the carport, while figure 4 shows a schematic three-dimensional view of it.
