The aim of this article is to introduce the designer to the broad range of long span, steel-based solutions that is available. 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 Composite Beams With Web OpeningsWeb openings are typically formed in beams to allow services to pass through the beam.

Steel structures. Steel is the major material for long-span structures. Bending structures originally developed for bridges, such as plate girders and trusses, are used in long-span buildings. Plate girders are welded from steel plates to make I beams that are deeper than the standard rolled shapes and that can span up to 60 metres (200 feet); however, they are not very efficient in their use of material.Conceptual design and analysis of long span structuresactivities.
