Abstract


Reinforcement and maintenance of the structure has become one of the hot issues of domestic and foreign research . FRP materials have high strength , lightweight , corrosion-resistant and anti-fatigue , etc. , are widely used in the reinforcement of civil engineering structures . In recent years , it is proposed \the purpose of the shear capacity . This is a promising FRP reinforcement method . The four-point bending tests of 10 reinforced concrete beams , Surface Mounted CFRP plate reinforced concrete beams bending performance , carried out a detailed description of the test process and phenomenon , and mainly for the following test results analyzed : 1 of CFRP plate reinforcement amount of change in the form of reinforcement beams destruction , carrying capacity . Summed up the law ; the 2 slotted size change and different slot arrangement of reinforcement BEAMS cracking load , bending stiffness and specimen ductility . Some regularity ; combined with test data , the use of the theoretical research and correct calculation formula with the test results , and revised the calculation of the parameters calculated results with the experimental results were compared on test data determine the accuracy and reasonableness of the correction factor ; addition of different reinforcement surface onlay CFRP reinforcement beam reinforcement performance , and given recommendations for engineering application .
