Steel trusses in buildings are used extensively to cover large clear spans and this article will mainly focus on this sort of construction. Roof trusses are an efficient means of supporting a roof covering for spans upwards of 20 m. Upper bound spans of 100 m are suggested on the steelconstruction.info web site.Timber trussed arch for long spanFor spans over 100m, trussed arches are usually preferred since they are more convenient to manufacture and to assembly. For instance, several buildings own such roof structures in Scandinavia. This masters thesis deals with Glulam trussed arches for long span. It especially focuses on an arch of 100m span and 20m height.Truss Frame | ClearSpanTrusses have long been a popular building component, because they take advantage of triangles fundamental strength. This design allows the ClearSpan Truss Arch Frame to distribute weight and stress across the entire truss for superior stability, while using minimal materials, saving the user money without sacrificing strength.
But in a long-span struc- ture with a supported area of 100,000 sq. ft, 5 psf translates into 500,000 lb of additional load that must be supported. Defining actual load criteria to reflect realistic conditions can significantly impact design.long-span trusses - American Institute of Steel Marquee Space.

The roof solution consists in using steel space trusses made out of square hollow sections (SHS). The truss has a clear span of 63.90m, a total length of 76,10m, a maximum height of 4,00m that is reduced on the length of the structural element, and a triangular cross section being 3,60m wide.Construction - Long-span buildings | BritannicaThey have varying optimum depth-to-span ratios ranging from 1 : 5 to 1 : 15 for the one-way truss to 1 : 35 to 1 : 40 for the space truss. The funicular structures include the parabolic arch, tunnel vault , and dome, which act in pure compression and which have a rise-to-span ratio of 1 : 10 to 1 : 2, and the cable-stayed roof, the bicycle wheel, and warped tension surfaces, which act in pure tension.Construction Control Techniques of Long-span Steel Truss long span steel space truss archSpace Mechanical Characteristics Analysis of Long-span Steel-trussed Arch Bridge at Construction Stage[J].
