Effective and convenient reinforcement schemes should be made combing with actual situation of proj ect . By adding steel beams and using rebar to connect old concrete beam and new steel beam , steelconcrete composite structure is made . Especially pay attention to connection of steel beam and concrete beam , and according reinforcing measurement are taken in bearing position of joints. Deformation after construction proved that the reinforcing construction is sucessful . Key wo
