Retrofit T-Shaped Reinforced Concrete Beams in Flexure and Shear Damage by Carbon Fiber Reinforced Polymer Sheets (CFRP)

To evaluate the effect of T-shaped reinforced concrete beams strengthened by bonding CFRP sheets by bending and shear resistance of epoxy resin, 6 Laboratory samples are designed, built and tested, due to the weakness of each of the three groups A , B, C are divided that group A was designed in a way that the beam has a moment of weakness in Group B if they were designed to do that beams with weak shear and group C was designed such that the beams were too weak and too weak shear, bending, combined bending and shear reinforcement to achieve the desired results. According to that in our country we often see a weakness in the concrete, all samples have been trying to make use of low strength concrete, so we can see that the first type of failure in concrete beams reinforced with what are weakness and secondly to increase the capacity for different conditions is how much boost.
