Behavior of Circular Concrete-Filled Steel Tube Columns ...

Apr 26, 2012  The behavior of concrete filled tube columns under seismic loads was studied through 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 strength.

Feb 01, 2007  Abstract. This paper presented an experimental study on the behavior of circular, concrete-filled, steel tube (CFT) stub columns with self-compacting concrete (SCC) and normal concrete (NC) concentrically loaded in compression to failure. Four measurement methods on the axial deformation of specimens were compared.
