Numerical Simulation on Retrofitting in Roof Corner Joint Strengthened With FRP Using FEM Method
International Journal for Research in Applied Science and Engineering Technology
Repair and strengthening of damaged or vulnerable reinforced concrete structures is important in order to guarantee the safety of residents or users. Beams are important structural elements for withstanding loads, so finding the efficient repair and strengthening methods are necessary in terms of maintaining the safety of the structures. This research study investigated various repair, retrofit, and strengthening techniques for reinforced concrete beams. The comparison and summary of each
... and strengthening method are provided in this thesis. The thesis involves the literature review of current experimental test of repair and strengthening techniques for reinforced concrete beams. Comparing the numerical investigation we can confirm that the deflection in the strengthened specimen is comparatively lesser than that of the un-strengthened specimen. It is observed that the stress in the specimen is better in the retrofitted with CFRP specimen when compared with the normal specimen without CFRP wrapping. 3. From the overall study, it can be concluded that the strengthening with CFRP structure will increase the serviceability of the structure. CFRP laminates reduces the deformation and stress 59% and 15.79% respectively With the help of this Simulative results we conclude that CFRP laminates provide more strength to the structure .
