Study on Accumulated Ductility Coefficient of Concrete Filled Steel Tubular Columns Based on Experimental Results

Abstract:

Article Preview

The hysteretic behaviors of concrete filled steel tube columns under low cyclic loads were analyzed for verification the accumulated energy dissipation performance. The accumulated ductility coefficient influencing factors, such as slenderness ratio, axial compression ratio and sectional steel ratio, were analyzed. It is indicated that these columns have a better energy dissipation capacity. The energy dissipation capacity decreases with the axial compression ratio increasing, but the influence of slenderness ratio and steel ratio to accumulated ductility coefficient is not clear, this is because the influence of difference loading system.
