Elements that Make a Roof Truss. Bearing: Structural support, usually a beam or wall, that is designed by the building designer to carry the truss reaction loads to the foundation. Bottom Chord: Inclined, or horizontal member that establishes the bottom of a truss, usually carrying combined tension and bending stresses. Cantilever: Part of a truss that extends beyond its support, exclusive of ...

A truss is an assembly of beams or other elements that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points.
