| Abstract: | Tests of carrying capacity of concrete filled steel tubular columns subjected to eccentric loads were carried out. Test parameters were load eccentricity ratio and material parameters (steel ratio, strength of concrete and confinement index). The test results indicated that both of the load eccentricity ratio and the material parameters affected the carrying capacity of CFST columns under eccentric load. With the load eccentricity ratio increased, the confinement of steel tube to core concrete and the ultimate carrying capacity of the column decreased. Finally, a comparison of the ultimate loads between test results and the predicated values by the six codes were analyzed and some suggestions for application were presented. |
