Long span structures
Beam structures
Structures consisting of beams supported on columns are simple and commonly used, especially where the minimum internal volume is required.
Claddings
The enclosures to the large sheds require particular attention to achieve performance and economy. Large uninterrupted areas of wall cladding demand clear simple statements and precise detailing.
Historical context
The development of long span buildings has closely followed technological progress and really started in the nineteenth century with the advent of the railways.
Masted structures
The concept of masted structures is not new, but they have only recently become popular as a means of providing lightweight structures for general use.
Portals and arches
Arches, which can take a variety of forms, are efficient structures for long span roofs.
Space frames
Space structures are efficient three-dimensional structural assemblies which can take a variety of forms.
Structural options
By far the most common structural material is steel due to its strength to weight ratio, ease of fabrication and cost.
Umbrella structures
The final option for consideration is the umbrella or tree structure in which the roof cantilevers from a central column and can be repeated and joined to other similar assemblies at each or any side to form a continuous structure.
