Behavior and strength of circular concrete-filled tube

2002-12-1  The behavior of concrete-filled tube columns under seismic loads was studied by testing six columns which were subjected to a constant axial load in addition to a cyclic lateral load. The test parameters included the level of axial load, the diameter-to-thickness ratio of the steel tube, and the concrete compressive strength.
