Overview Historically beams were squared timbers but are also metal, stone, or combinations of wood and metal<ref>"Beam" def. 1. Whitney, William Dwight, and Benjamin E. Smith.

Beams generally carry vertical gravitational forces but can also be used to carry horizontal loads (e.g., loads due to an earthquake or wind or in tension to resist rafter thrust as a tie beam or (usually) compression as a collar beam). The loads carried by a beam are transferred to columns, walls, or girders, which then transfer the force to adjacent structural compression members. In light frame construction joists may rest on beams.
