【 摘 要 】

At present, the research on basalt fibre reinforced polymer (BFRP) at home and abroad is still in the initial stage, and the research on strengthening beams mostly focuses on strengthening simply supported beams, while the research on strengthening reinforced concrete continuous beams with BFRP is still rare. In this paper, the finite element method is used to simulate the reinforced concrete continuous beam strengthened with BFRP, and the results of cracking load, ultimate load, stiffness and deflection are obtained. The results show that ABAQUS can simulate the relevant mechanical properties of the strengthened beam. It provides effective guidance for the design and application of reinforced concrete continuous beam strengthened with BFRP.
