A Study on Experimental on Bending-Shear Behavior of Concrete-Filled Double Skin Steel Tubular Beams

Abstract:

This study examined the effects of the inside-outside diameter ratio (D_i/D₀), concrete strength, and inside-outside reinforcement type of steel tube on the structural behavior of concrete-filled double-skin steel tubular (CFDT) beams. Towards this end, the failure type, load-deflection relationship, ultimate strength, and displacement ductility were compared and analyzed. The results showed that the maximum load-deflection and failure type are affected by the D_i/D₀ and the reinforcement method. Furthermore, the higher the D_i/D₀ was, the lower the restraint stress and maximum load became.
