Abstract
This paper presents an experimental study on the flexural behavior of bonded prestressed concrete (PC) beams strenthening using CFRP sheet. Two (PC) beams were fabricated, with overall dimensions of 150 × 200 × 2700 mm. One specimen served as an unstrengthened control, while the other was strengthened using CFRP sheets to enhance flexural performance. The specimens were simply supported and subjected to a four-point bending test until failure, allowing assessment of their flexural behavior. The results show that the CFRP-strengthened PC beams exhibited a 24% increase in load-bearing capacity compared to the control specimen. The stiffness of the strengthened beams was also significantly enhanced, leading to a reduction in deflection. Based on the obtained results, it is evident that the application of CFRP sheets for strengthening PC beams is a viable solution.
