This study examines the eccentric compressive performance of concrete-filled steel tube columns reinforced with annular stiffeners.
Conducted eccentric compression tests on CFST columns.
Developed a refined finite element model for deeper analysis.
Performed comprehensive parametric analysis on design parameters.
Annular stiffeners provide strong confinement to core concrete, resulting in higher stresses at ultimate state.
Increased concrete strength raises the balanced failure point of the interaction curve.
Proposed design formulas predict ultimate eccentric bearing capacity with high accuracy against experimental results.
