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. ... Trusses consist of triangular units constructed with straight members.

What is the purpose of a truss?

A truss gives a stable form capable of supporting considerable external load over a large span with the component parts stressed primarily in axial tension or compression. The individual pieces intersect at truss joints, or panel points.

Why do builders use trusses?

Because they are engineered, trusses can support more weight over longer spans as well. ... With engineered truss floor and roof systems there is less deflection and movement, which prevents creaky floors and makes the overall structure of the home stronger.
