Abstract In this work, the cracked concrete members are repaired, strengthened and reinforced by the inlaying method to ensure that the concrete members have not less than the initial mechanical properties before the cracking. In this work, the flexural test of the inlaid concrete members is carried out, and the bearing capacity calculation is carried out based on the material mechanics theory. Then the finite element model of the ABAQUS construction example is used to observe the stress distribution during the deformation process, and the repaired concrete is studied. Elastoplastic performance and further optimize the performance of the insert. The results of analytical tests, theoretical numerical calculations and finite element analysis show that the inlaid reinforcement method studied in this work has significantly improved the flexural performance of cracked cement products. The finite element software can be used to replace the experimental work in the next study,and inlaid reinforced concrete structure technology should be further studied.
