Stress Analysis of Axial Compression Steel Reinforced Concrete Column under High-Temperature Fire
Based on the fact that building material strength degeneration rules in domestic and overseas are different under the high-temperature fire, with the program ANSYS, the temperature stress distribution of cross-section is obtained and the two results are compared according to stress analysis of numerical simulation on the axial compression steel reinforced concrete column (ACSRCC) under high-temperature fire. Based on the conversion principle of different materials stress and the superposition principle, the numerical calculation method on cross-section stress of ACSRCC under high-temperature fire is proposed, and the calculated results agree with simulation data well. The influences of the concrete coverage thickness and other factors on ACSRCC mechanical properties under high-temperature fire are also discussed in the paper.
