Abstract In this work, ABAQUS finite element software was used to calculate the finite element numerical simulation of the concrete members strengt-hened with dumbbell-shaped inserts. The influence of the geometry of the inserts on the reinforcement effect was analyzed. The shape of the eight inserts was selected and the dumbbell-shaped inlay reinforcement was compared and analyzed. After the joint length and radius of the two ends of the joint are strenghened, the intermediate crack extrusion, boundary effect and its influence on the ultimate bearing capacity were emphasized. The results show that ABAQUS software can be used in the research. The radius of the shield head and the increase of the joint length of the dumbbell-shaped inlaid reinforcement can significantly improve the ultimate bearing capacity of the concrete members after reinforcement, and provide reference for further research and expansion of the research work and engineering practice of the inlaid reinforced concrete members.
