In order to solve the problem that the steel bar spacing is too small when the amount of steel bars in the concrete structure is large in engineering practice, a method of arranging the longitudinal stressed steel bars and reinforcing them is proposed. According to the results of 31 reinforced bonded anchoring drawing specimens, the stress performance test of 17 reinforced concrete reinforced beams was carried out, and the characteristics of bonded anchoring of reinforced beams and the main factors affecting bonded anchoring were discussed in detail, and compared with general beams. The experimental results show that the bonding and anchoring performance between steel and concrete decreases after the use of reinforcement, but the bond-slip characteristics are similar to those of general beams, and the anchoring strength and bearing capacity of the reinforced beams can be guaranteed by extending the anchoring length appropriately, so that the reinforced beams can be applied in engineering practice. The suggested formula for calculating the anchorage length of the reinforcements is given, and the calculation results are consistent with the test results
