Experimental study to use steel plate bonding for rehabilitation hollow core slabs and improve its behavior

For many years, reinforced concrete structures have been reinforced in civil engineering through the external bonding approach. This research presents an experimental study to determine the effect of using steel plate to treat cracks on the behavior of a hollow core slab cast with normal-strength concrete. The experimental program includes testing four hollow concrete slabs with dimensions (1200 x 400 x 100 mm) and (1200 x 500 x 200 mm). Reinforce it with reinforcing bars. Experimental results showed that Bonding steel plates to the tension face of reinforced concrete slabs increased the bending moment resistance significantly.
