		+	== Belfast Truss ==
		+
		+	The Belfast Truss is truss consisting of a lower horizontal member or tie-beam and a curved upper member or bow which has smaller intersecting members at various points, in a fan grid or lattice-like pattern. The upper curved member has a radius which is half that of the setting out point for the fanning lines.

Trusses are most commonly used in bridges, roofs and towers.

	A truss is made up of a web of triangles joined together to enable the even distribution of weight and the handling of changing tension and compression without bending or shearing. The triangle is geometrically stable when compared to a four (or more) -sided shape which requires that the corner joints are fixed to prevent shearing.

−	== ~~ratt~~ truss ==	+	== Pratt truss ==

	Also known as an ‘N’ truss, this form is often used in long-span buildings, with spans ranging from 20-100 m, where uplift loads may be predominant, such as in aircraft hangers. A Pratt truss uses vertical members for compression and horizontal members for tension. The configuration of the members means that longer diagonal members are only in tension for gravity load effects which allows them to be used more efficiently.

−	== ~~arren~~ truss ==	+	== Warren truss ==

	A Warren truss has fewer members than a Pratt truss and has diagonal members which are alternatively in tension and compression. The truss members form a series of equilateral triangles, alternating up and down.

−	== ~~orth~~ light truss ==	+	== North light truss ==

	This form of truss is usually used for short spans in industrial buildings, and is so called because it allows maximum benefit to be gained from natural lighting by the use of glazing on the steeper north-facing pitch (sometimes referred to as a sawtooth roof). It is common, on the steeper sloping portion of the truss, to have a second truss running perpendicular to the plane of the north light truss, providing large column-free space.

	Typically made from timber, and spanning up to 8m, king post trusses are commonly used in the construction of domestic roofs. They take the form of a simple triangle, with a vertical member between the apex and the bottom chord.
