Description	Journal: Iop Conference Series: Earth and Environmental Science In order to study the characteristics of the temperature field and variation law of steel pipe recycled aggregate concrete column in a fire hazard, this paper takes the thickness of steel pipe and the type of concrete material as the main parameters to carry out fire resistance test of six concrete steel columns simulated by ABAQUS and conducts finite element analysis of the temperature field inside the test piece. The result shows that both the steel pipe recycled concrete column and the ordinary steel tube concrete column have a temperature platform during heating, and their temperature rise is feature hysteresis; the thickness of the steel pipe has little effect on the internal temperature rise while the concrete material is the main factor affecting the heating rate, so steel pipe recycled aggregate concrete column is better fire-resistant. The constitutive model based on the modified parameters in European EC4 specification is used for finite element analysis, and the FEM simulation result is well fitted with the experimental data.
