Abstract:
The paper presents an experimental activity carried out on RC beams strengthened in flexure and shear with different configurations of CFRP laminates. Currently many building and other structure are deteriorated due to age or poor construction. There are many techniques used for retrofitting purpose like jacketing, fiber reinforced polymer (FRP) wrapping etc. This research is basically to strengthen and redesign existing structure. This research work includes Strengthening of full size beam (150mm*150mm*1000mm). Flexure or shear-critical beams were provided with CFRP longitudinal sheets like single layer, double layers etc or U-wraps, respectively. Flexure–shear critical beams were provided with shear or combined systems. Concrete beams reinforced internally with steel and externally with carbon FRP. Laminate applied after the concrete had cracked were tested under two-point bending. Result show that FRP is very effective for flexural strengthening. Different type of wrapping of the FRP laminate combined with adhesive bonding is effective in anchoring the laminate.
