Behavior of reinforced concrete beam with CFRP and GFRP laminates

ABSTRACT

The main aim is to examine the behavior of laminated carbon fiber and glass fiber reinforced polymer (CFRP) and (GFRP) reinforced composite (RC) beams. The physical characteristics of these laminates, such as tensile strength, modulus of elasticity and strain capacity are examined. The capacity of load bearing, deflection, and cracking behavior of RCC beam specimens along with various types and numbers of laminates will be analyzed and compared. The results will provide insight into the outcome of using different kinds of laminates over RCC beams and identify the optimal configuration for their reinforcement. The findings of this research paper will have significant implications for the construction industry, particularly for rehabilitation and repairing of old buildings and other structures. The use of CFRP and GFRP laminates as a reinforcement material can extend the life of RCC beams, reduce the need for costly repairs and replacements, and increase the safety and sustainability of infrastructure. The paper will conclude with recommendations for the optimal use of carbon fiber and glass fiber reinforced polymer laminates in RCC beam reinforcement, including the selection of appropriate materials and design criteria for their successful application.
