STRENGTHENING OF REINFORCED AND PRESTRESSED BEAMS

To strengthen this beam, a steel channel is fixed to the bottom of the beam in such a way that the web of the channel forms the new soffit of the beam. The channel is held in position by bolts passing through holes drilled in the flanges of the steel channel and in the web of the concrete beam above the longitudinal reinforcement.

What is a Concrete Beam? (with pictures) - Info Bloom

Sonal Panse Concrete beams are widely used in contemporary building construction. In structural engineering, a concrete beam is a load-bearing unit that can be used to carry both horizontal and vertical loads.Known as reinforced concrete beams or reinforced cement concrete (RCC) beams, these beams are made by encasing steel bars, plates, or fibers within the concrete.
