Abstract |
|
A crisscross section column composed of concrete-filled square steel tubes was tested in axial loading up to failure. The column was analyzed by the finite element method and the ultimate load as well as the failure mode were in agreement with the experimental findings. An analytical method was also proposed which when applied to the tested column gave an estimate of the ultimate load about 4% different from the experimental. The analytical method also predicted the mode of failure correctly. |
