Abstract:
As part of a research program on the behavior under load of high-strength concrete-filled steel tubular (CFST) columns, a series of tests has been undertaken to study the influence of the shear transfer by bond between the infill concrete and the inner surface of the circular steel tube. Three different cases of bond were examined together with four different loading regimes and slenderness ratios. Companion tests on similar empty steel tubes were also undertaken to highlight the synergistic effect of the steel and concrete acting compositely together. Conclusions are drawn on the significance of bond in the columns tested in this investigation
