ABSTRACT

Over the last few decades, the use of fiber-reinforced polymer (FRP) composites has emerged as one of the most effective and promising methods for strengthening and rehabilitating reinforced concrete (RC) structures, aiming to enhance their performance and extend their service life. Among the evolving innovations in the FRP family, BFRP stands out as a fresh and compelling solution, combining strength, durability, and affordability, ushering in a new era of efficient structural rehabilitation. In this work, seven continuous RC beams, each with an overall length of four meters, were loaded and then rehabilitated to improve the shear resistance using different types of BFRP and CFRP materials for comparison purposes. The same patterns of rehabilitation were applied to both FRP materials to facilitate comparison with the reference sample and assess the effectiveness of the rehabilitation. The experimental findings demonstrated a notable increase in shear strength due to FRP rehabilitation, with BFRP enhancements ranging from 34.4% to 77% and CFRP improvements varying between 16.4% and 98.7%. These results highlight the considerable load-bearing capacity provided by both materials, with BFRP emerging as a more economical option. The observed experimental behavior showed strong agreement with both Finite Element Modeling predictions and theoretical calculations, underscoring the effectiveness and reliability of FRP materials in the structural rehabilitation of RC beams.
