Abstract:
Based on the unified strength theory, the axial ultimate bearing capacities of square steel tube short columns filled with steel-reinforced self-consolidating high-strength concrete under three-dimensional stress were analyzed. By introducing the equivalent constraints reduction factor and concrete strength reduction factor, which respectively considered the influence of thickness-length ratio and scale effect, the confinement of square steel tube towards concrete was equivalent to the confinement of circular steel tube towards it. Thus, the formulas for calculating ultimate bearing capacity of the square steel tube short columns filled with steel-reinforced self-compacting high-strength concrete were deduced. A reasonable match was reached by comparing the results calculated by the formulas with the test results and the calculated result of existed formulas. The result shows that the formulas have significances in exerting material potentials and saving materials, and also provide the important basis for structural analysis.
