Truss

A truss is a structure that has beams, called members, across a structure such as a building or bridge to give it more support.^[1]

Types

There are two basic types of truss:

• The pitched truss, or common truss, uses triangular shaped bases. It is most often used for roof construction.
• The parallel chord truss, or flat truss, gets its name from its parallel top and bottom chords. It is often used for floor construction.
