Based on experimental research on plain concrete columns with high strength concrete core, the formula to predict the bearing capacity of concrete columns with high strength concrete core under axial compression loading was brought forward in previous paper, in order to verify the formula whether right, axial compression test including 3 concrete columns with high strength concrete core and 1 ordinary reinforced concrete column were completed, and the failure characteristic was analyzed additionally. According to experimental results, it can be shown that the failure modes of concrete columns with high strength concrete core are similar to that of ordinary reinforced concrete columns, however, the bearing capacity of concrete columns with high strength concrete core is significant higher compared with that of ordinary reinforced concrete column; the results of the bearing capacity obtained by the formula (2) was in good agreement with the experimental results.

Steel Reinforced Concrete

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.
