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. 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.
