Beam (structure)

A beam is a structural element that carries structural load.

A beam that bends under an evenly-distributed load

Beams generally carry vertical forces but can also be used to carry horizontal loads (those loads can result from winds or earthquakes). The loads that a beam carries are led to columns or walls, which lead the force to the next element.

Beams are characterized by their profile (their shape), their length, and their material. Today, most construction has beams that are made of steel, reinforced concrete, or wood.
