BEHAVIOUR OF REINFORCED CONCRETE BEAM STRENGTHENED WITH GFRP
Journal Title: Engineering and Technology Journal - Year 2017, Vol 2, Issue 8
Abstract
To carry out studies some experimental investigations were done on behaviour of RC beams strengthened in flexural and shear by means of GFRP laminates. Outwardly epoxy-bonded GFRP sheets reinforced concrete beams were tested to failure using a two point concentrated static loading system. For this experimental investigation three sets of beams were casted test program. In first set of three beams were casted which were weak in flexure, among them one was controlled beam and rest two beams were strengthened by means of continuous glass fiber reinforced polymer (GFRP) sheets in flexure. For second set, three beams were casted but they were weak in shear, and again among them one was the control beam and left over two beams were strengthened by means of continuous glass fibre reinforced polymer (GFRP) sheets in shear. For third set, three T beams were casted, having one controlled beam along with two beams which were strengthened with GFRP Different amount and configuration was to strengthen the beams with the help of GFRP sheets. For each of the beams experimental data for load and their corresponding deflection were recorded. Also the detailed procedure and their application for strengthening RC beams are included. The orientation of GFRP layers and its effect of number on ultimate load carrying capacity is studied along with this failure mode of the beams are investigated
