ANALYTICAL STUDY OF RC BEAM EXTERNALLY BONDED WITH GFRP SHEETS

  • Abstract:
  • The use of externally bonded Fiber Reinforced Polymer (FRP) sheets is an effective method for enhancing the strength, stiffness, and service life of reinforced concrete (RC) structures. This study analyzes the structural behavior of RC plate girders strengthened with Glass Fiber Reinforced Polymer (GFRP) sheets under loading conditions. A finite element model (FEM) in ABAQUS is developed to evaluate improvements in flexural strength, deflection control, and stress distribution. The results indicate that GFRP strengthening enhances load-bearing capacity, mitigates deflection under service loads, and improves shear performance. This study provides insights into the effectiveness of GFRP sheets as a cost-efficient, lightweight, and durable strengthening solution, aiding in the development of practical design guidelines for deteriorating infrastructure.
