Research on Axial Behavior of Thin-Walled T-Shaped Steel Stub Columns Filled with Recycled Demolished Concrete Lump
An axial compression test has been done on 12 short columns, ribbed and spiral stirrup short column filled with recycled demolished concrete lump to study the axial compression variable characteristics and ultimate bearing capacity of thin-wall T-shaped steel tube column filled with recycled demolished concrete lump. The load displacement curve has been analyzed, ultimate bearing capacity of standard formula has been compared and the reliability of finite element numerical simulation and been discussed. The result shown that the form of steel tube embedded with structural members has more effectively increased the tensility, delayed bending occurrence, enhanced the effect of restraint of core concrete and increased the ultimate bearing capacity than that the form of plain section form. The ultimate bearing capacity of ribbed form has been increased by 16.76% than non-ribbed form, and the ultimate bearing capacity of spiral stirrup form has been increased by 11.98 % than non-spiral stirrup form. The finite element simulation and the test result was identical properly.
