USE OF GLASS FRP SHEETS AS EXTERNAL FLEXURAL REINFORCEMENT IN RCC BEAM

The maintenance, rehabilitation and upgrading of structural members is perhaps one of the most crucial problems in civil engineering applications. This could manifest itself by poor performance under service loading, in the form of excessive deflections and cracking, or there could be inadequate ultimate strength. Additionally, revisions in structural design and loading codes may render many structures previously thought to be satisfactory, noncompliant with current provisions. This research study presents to Study the Effect of Different Strengthening Patterns Using GFRP (Glass Fibre Reinforced Polymer) on Flexural strength of the Beam. Totally six rectangular beams having 1500 mm x 100 mm x 200mm were casted. The grades of concrete M20. Flexural strength test, using simple beam with two- point loading was adopted in Frame loading testing Machine to study for the performance of GFRP wrapped beams in terms of increase in flexural capacity and deflection and it was compared with the control beams. The test results show that the beams flexural with GFRP laminates exhibit better performance. Three main variables namely, strength, ductility and damage level of R.C.C. under reinforced beam and R.C.C. beam weak in flexure were investigated. Comparison has been made between results of two sets.
