Abstract :

Worldwide a great deal of research is currently being conducted concerning the use of fiber reinforced plastic wraps, laminates and sheets in the repair and strengthening of   reinforced concrete members. Fiber reinforced polymer (FRP) application is a very effective way to repair and strengthen structures that have become structurally weak over their life span. FRP repair systems provide on economically viable to alternative to traditional repair systems and materials. Experimental investigations of flexural behaviour of RC beams strengthened by using glass fiber reinforced polymer sheets are carried out. Externally reinforced concrete beams with Epoxy bonded GFRP sheets were tested to failure using a symmetrical two point concentrated static loading system. Two sets of beams were casted for this experimental test program. The beam casted as weak in flexure and strengthened using glass fibre reinforced polymer sheets out of two beam another is controlled beam. The strengthening of the beam is done with different amount and configuration of GFRP sheets. Experimental Data on load, deflection and failure modes of each of the beams were obtained. The detail procedure and application of GFRP sheets for strengthening of RC beam is also included. The effect of number of GFRP layers and its orientation on ultimate load carrying capacity and failure mode of the beams are investigated.
