Reinforced concrete columns have good load-carrying capacity, that are widely used in structures. However, the internal steel reinforcement can easily corrode as well. It has a large influence on electromagnetism, etc., which is not suitable for use in high salt corrosion areas and areas with little electromagnetic interference. In recent years, the emergence of BFRP-reinforced concrete columns is expected to solve the above dilemma. In this study, seven groups of concrete column specimens with different reinforcement (rebar, BFRP, BFRP steel hybrid bar) were tested for compressive load capacity, and the three types of concrete columns belong to the material damage, and the load carrying capacity of reinforced concrete columns is greater than that of hybrid bar columns and much greater than that of BFRP bars, so the BFRP bars and hybrid bar columns can only be used in the low load-bearing structure, and how to improve their load carrying capacity is an important direction for future research. Therefore, BFRP bars and hybrid bars can only be used in low load-bearing structures, and how to improve their load-bearing capacity is an important direction for future research.
