Popis:	In order to study the effect of different ratios of steel plate strengthening the bottom of reinforced concrete beams on the mechanical properties of the beam, based on the area of the bottom of the beam, various steel plate reinforcement schemes of 25%, 50%, 75% and 100% were designed. ABAQUS is used for static load calculation and comparative analysis with unreinforced reinforced concrete. The results show that : (1) Different ratios of steel plate strengthening the bottom of reinforced concrete beam can improve the bearing capacity of the beam, but the growth of the bearing capacity slows down after the steel plate ratio reaches 75% of the area of the beam bottom; (2) Reinforcing steel plates with different ratios at the bottom of the beam can improve the flexural performance of the beam. It is suggested that the steel plate reinforcement ratio should be selected reasonably in engineering practice.
