The provision of openings in beams is to facilitate the passage of utility pipes and ducts. So, a considerable reduction in the depth between the ceiling and the floor above is achieved, which also translates into substantial savings in the construction of a multi-storey building. However, current Indian code of practice of construction of building structures do not provide provision for design of beam with openings. In present study, a total 10 beams of size 1800 x 150 x 300 mm were prepared with two openings of 120 x 120 mm provided in the shear zone. Three beams were strengthened and three beams were rehabilitated with CFRP sheets and tested under flexure, load carrying capacity and cracking pattern were studied and it is found that strengthened and repaired beams were effective and overcomes the actual strength and deflection in rehabilitated beams more over controlled opening beams. Furthermore the cracking pattern, modes of failure and cracking distance in shear and flexure were presented and compared with controlled beams.
