Uniaxial behaviour of confined high-strength concrete-filled-steel-tube columns
2014
Proceedings of the Institution of Civil Engineers : Structures and buildings
High-strength concrete (HSC) columns are usually provided with heavy confining steel within the potential plastic hinge region to restore flexural ductility. However, as the effectiveness of confining steel decreases with the concrete strength, the required confining steel content for high-strength concrete columns becomes very large, which causes steel congestion in the proximity of beam-column joints. A better method is to adopt a concrete-filled-steel-tube (CFST) column, which uses a hollow
