Abstract: In this paper results of tests conducted on 27 concrete-filled steel tubular columns are reported.
The test parameters were the column slenderness, the load eccentricity covering axially and eccentrically loaded columns with single or double curvature bending and the compressive strength of the concrete core.
The test results demonstrate the influence of these parameters on the strength and behaviour of concrete-filled steel tubular columns.
A comparison of experimental failure loads with the predicted failure loads in accordance with the method described in Eurocode 4 Part 1.
1 showed good agreement for axially and eccentrically loaded columns with single curvature bending whereas for columns with double curvature bending the Eurocode loads were higher and on the unsafe side.
More tests are needed for the case of double curvature bending.
