The Design Method Of Strengthened RC Beam With Carbon Fiber Reinforced Polymer Sheet And Engineering Practicality

This thesis is based on a great deal of tests of concrete beams strengthened with carbon fiber reinforced polymer in internal and external, indicate the relationship of stress-stain and load-strain cracks rigidity and strengths extension and measure to prevent debonding of strengthened RC beam. The types of destruction of the strengthened RC beam and the factors to influence the effect of the strengthened RC beam is analyzed. A calculation method for the flexuarl and shear CFRP strengthened beam is put forward, and use it into practical work.
