ANALYSIS OF RCC BEAM WITH OPENING STRENGTHENED BY FRP USING FINITE ELEMENT APPROACH

Abstract: To accommodate important utilities such as power, telephone, computer network, and air conditioning, modern construction structures require numerous pipes and ducts. This will produce extra void space or waste space thus, a substitute arrangement must be devised to transmit these pipes and ducts via a transverse passage of the beam, and the cost of the construction of structures can be decreased. Hence, strengthening a beam with an opening should be done. There are two types of strengthening of beams: The pre-planned opening is done by steel reinforcement should be provided with proper design. When a post-planned opening occurs, the beam should be reinforced with different FRP such as CFRP, GFRP, and other materials. Different investigation has been done for reinforced structural member beams with openings. The main aim of this paper is to tell about the performance of the beam opening, analyse using the software, and design of concrete beam opening. Furthermore, various classifications of opening, different opening site suggestions, and the performance of Reinforced concrete beams with openings will be highlighted and explored. The article will also detail and explain many design methodologies. There are different types of strengthening techniques of the beam such as Fibre Reinforced Polymer and steel plates are investigated for strengthening RCC beams with openings.
