What are long span structures?
What we consider long span structures are structures with spans larger than 20 meters. The most common types of long-span structures are trusses, folded plates, shell structures, frames, and tent structures or tensile structures.
How far can structural steel span?
When it comes to residential projects like houses and smaller buildings, you can expect a steel beam to be eight inches wide. This allows it to span as much as 12 feet before you need another column. Some beams can be 10 inches wide, which will translate to a 14-foot span, at a bare minimum.
What is long span beam?
Long Span Beams Long Span Trusses Portal Frames Introduction Beams greater than 30 meters in span are said to be LONG SPAN BEAMS. The use of long span beams results in a range of benefits, including flexible, column free internal spaces, reduced foundation costs, and reduced steel erection times.
How long is long span structure?
Long-span buildings create unobstructed, column-free spaces greater than 30 metres (100 feet) for a variety of functions.
What is the span of a beam?
Span is the distance between two intermediate supports for a structure, e.g. a beam or a bridge. A span can be closed by a solid beam or by a rope.
Can a steel beam span 20m?
Spans in excess of 20 m can be achieved (for the purposes of this article the definition of long span is taken as anything in excess of 12 m). Generally long spans result in flexible, column-free internal spaces, reduce substructure costs, and reduce steel erection times.
How far can I span a beam?
The maximum distance a 2×6 can span, according to the 2018 IRC, for a floor joist, is 12′-6”, ceiling joist 20′-8”, rafter 18′-0”, deck board 24”, deck joist 9′-11”, deck beam 8′-3”, and 6′-1” as for header. Always check the codes for determining factors or consult a Structural Engineer.
What is the definition of a long span building?

What are the guidelines for long span steel beams?
The design of long span steel and (steel-concrete) composite beams is generally carried out in accordance with BS 5950, BS EN 1993 or BS EN 1994. For some types of beam this codified guidance is complemented by specific design guidance, such as that on the design of beams with large web openings (see SCI P355 ), or manufacturers’ information.
How big should a long span hangar be?
A study, on the Efficient Design of Large span hangars/structures, ensuring lighter foundations is presented. Structure with Span larger than 40 m can be regarded as long span structures and need to be carefully designed keeping a balance of all the aspects like its weight, deflections (sway) and foundation forces.
