Axial Compressive Behavior of Self-Stressing Steel Slag Aggregate Concrete Filled Steel Tubular Columns With Bond-Slip Damage
Abstract:The axial compressive behavior of self-stressing steel slag aggregate concrete filled steel tubular (CFST) columns with bond-slip damage is investigated in this paper. Six bond-slip damaged specimens and two undamaged specimens with different diameter-thickness ratios and expansion ratios are tested. According to the test, the outward deformation dominates the failure of the axial loaded bond-slip damaged specimens. The ultimate bearing capacity is lower with higher diameter-thickness ratio, while the increase… Show more
