Reinforced Concrete Beams: 

Reinforced concrete beams are used in all manner of concrete framed buildings including residential buildings, offices, car parks and many other structures. Reinforced concrete is economical as it allows a very small quantity of steel very effectively by placing this steel at exactly where it is most effective at the bottom of the section. The concrete provides the lever arm and depth for the steel. The concrete also resists the compressive forces at the top of the beam and provides a durable cover for the steel.
