FLEXURAL RESPONSE OF FRC BEAMS WITH EXTERNAL GFRP LAMINATES
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2012, Vol 3, Issue 12
Abstract
This study presents the experimental results of steel fibre reinforced concrete beams with externally bonded glass fibre reinforced polymer laminates with a view to study their strength and ductility. Three types of beams were tested in the laboratory. Three fibre reinforced concrete beams were used as reference beams. Six fibre reinforced concrete beams were provided with externally bonded GFRP laminates. One concrete beam was left virgin without any fibre reinforcement and external GFRP laminates. All the beams were tested until failure. The variables considered included volume fraction of fibre reinforcement and stiffness of Glass fibre reinforced polymer laminates. The static responses of all the beams were evaluated in terms of strength, stiffness and ductility. The experimental results show that the beams provided with steel fibres and externally bonded glass fibre reinforced polymer laminates exhibit improved performance in all the aspects over the beams with internal fibre reinforcement.
