| Abstract: | A Self-compacting concrete-filled circular steel tubular columns were tested for the f ire resisitance, the measure content including: the temperature on surface of steel, the relations of axial deformation and time, and the relations of deflection and time. And the influence of many factors on the ultimate strength, axial deformation and deflection of self-compacting concrete-filled steel tubular columns is analyzed. It includesthe steel ratio, the load eccentricity ratio, ratio of axial compressive force ... |
