A truss is essentially a triangulated system of straight interconnected structural elements. The most common use of trusses is in buildings, where support to roofs, the floors and internal loading such as services and suspended ceilings, are readily provided. 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. It consists of a frame of axially loaded members that are either in tension or compression and are interconnected at the joints. Trusses are structurally engineered to be efficient structural systems where every component is critical to the long-term durability and strength of the truss.
