Abstract：
In this paper, the thermal parameters of recycled concrete and recycled concrete and the replacement rate of recycled aggregate concrete are calculated. The finite element model is used to simulate the constitutive relation of outer steel tube and recycled concrete under high temperature. Combined with a high temperature fire resistance test explores the reinforcement, including the impact of steel ratio, load bearing capacity of reinforced steel ratio of recycled concrete columns and reasonable reinforcement ratio.
