General Information

Figure 1 shows a schematic three-dimensional view of a freestanding steel carport.

The steel structure consists mainly of five truss columns, five knee-braced beams, a tie truss, purlins, and metal roofing sheets.

Carport Foundation

Figure 2 shows the carport after a wind storm.

The wind storm caused a global stability failure. Figure 3 shows a truss column base.

The two chords are welded to a thin base plate; an asphalt layer over it (approximately 4 cm) and gravel and sand under it are noticeable. Figure 4 shows a further truss column base.

The front sector of the base plate is missing; a horizontal rebar and gravel and sand under the base plate are noticeable.
