Structural Behaviour of Reinforced Concrete (RC) Deep Beam with Web Opening Strengthened using Carbon Fibre Reinforced Polymer (CFRP)

These days, construction is more towards the high-rise building and a deep
beam is considered as one of the structure that always caught structural engineers’
interest as it is used as transfer girders, foundation pile caps as well as wall footings.
The deep beam which having small span to depth ratio will transfer the external load
to the support through compression action and it is said that the shear failure is most
likely to happen in deep beam instead of normal beam. This experimental study aimed
at examining the structural behaviour of the reinforced concrete (RC) deep beam
having an opening strengthened using Carbon Fibre Reinforced Polymer (CFRP) in
the shear zone. Total of 9 RC deep beams with opening and one without opening which
acts as a control beam having a dimension of 2000mm x 130mm and 500mm in height
were fabricated and tested at the lab to check for the structural behaviour such as failure
mode, load-deflection behaviour, crack pattern of the beam. The beams were tested
with two symmetrical loads, each located 850mm from the edges of the beam after the
CFRP was attached around the opening.
