Title: Steel-wood system

Abstract: A web-reinforced wood joist defines a top edge surface, a bottom edge surface opposite to the top edge surface, a first lateral web surface, and a second lateral web surface opposite to the first lateral web surface. A longitudinal metal reinforcement is applied to at least one of the first and second lateral web surfaces. This metal reinforcement includes at least one sheet metal strip formed with integral teeth distributed at predetermined intervals along the entire length thereof and driven into the wood to fixedly secure the metal reinforcement to the joist's wood. This web-reinforcing method is suitable to reinforce any type of elongated structural wood members to improve their strength in bending, direct tension, direct compression, direct shearing and any combination thereof.
