Abstract - Modern buildings contain a lot of pipes and ducts for essential utilities like electricity, telephone, internet, and air conditioning. Installing all of these can take up a lot of space, leaving behind empty areas that serve no purpose. To  through the beam to accommodate the pipes and ducts, reducing the amount of unused space and lowering construction costs. To achieve this, a beam can be strengthened with an opening. Several investigations have been conducted regarding structural reinforced beams with openings. The aim of this paper is to describe the effectiveness of the opening in the beam. In addition, this paper will focus on several types of opening classifications, varied recommendations for opening placement, and an analysis of the effectiveness of reinforced concrete beams that contain openings. The practical way to reduce the of beam strength brought on by such holes is to reinforced concrete (RC) beams using externally bonded fibre reinforced polymer (FRP) sheets, strips, or steel plates. This paper examines the use of CARBON FIBER REINFORCED POLYMER (CFRP) to strengthened and repair the structures.

Key Words:  CFRP laminates, RC beams, opening of beams, failure crack pattern, strengthening of beams.
