Bonded Concrete Beam with CFRP and GFRP Layers: Evaluation of Strength and Weight (original) (raw)

Simulation of the CFRP and GFRP layers to study their effect on the strength of the structural beam has been studied in the present paper. CFRP (carbon fiber reinforced polymer) and GFRP (glass fiber reinforced polymer) as an added layer over the structural beam has been studied in detail. Four sets of simulation have been conducted, one is simple concrete beam, second having one layer of FRP, third having two layer of FRP and fourth having one FRP layer plus reinforcement over the structural beam respectively. FRP materials have low weight and high resistance skills which makes them suitable for strengthening applications. ANSYS has been used to simulate the FRP layers with structural beam to study the effect of it on the beam strength and weight. To study the effect of the FRP layers, total deformation and weight under a loading condition have been compared. Results reveal that the FRP layers strengthen the structural beam. From the results it has also concluded that the same dimensions structural beam having FRP layers are lighter in weight compared to same dimensions conventional structural beam. FRP (CFRP & GFRP) materials in place of the concrete decreases the total deformation occurs in the beam under a loading condition. CFRP shows less deformation and are also lighter in compared to GFRP. Reinforcement inside the concrete beam with one layer of FRP decreases the total deformation occurs in the beam.
