Abstract     [Full Text]
    Concrete-filled steel tubular (CFT) columns are commonly used in engineering structures and always subjected to torsion in practice. This paper is thus devoted to investigate the mechanical behavior of circular CFT columns under pure torsion.3D finite element models based on reasonable material constitutive relation were established for analyzing the load-strain (T-–
 
Key Words
    concrete-filled steel tube (CFT); pure torsion; finite element; ultimate bearing capacity; confinement effect
