Abstract
Single concrete filled steel tube (CFST) members are widely used in building structures and bridges due to their high strength, ductility, toughness, fire resistance[1], energy absorption capacity, fast track construction and low cost, which is due to the composite action between steel tube and core concrete. This study examines structural performance of composite columns comprising of concrete filled steel tubes connected with double corrugated plate. T-shape, C-shape and Z-shaped sections are selected for this study. Non-linear finite element (FE) model was developed using ANSYS 16.1 to study structural performance of these special shaped CFST columns (SCFST). SCFST columns were analysed under axial compression, eccentric and lateral loads. Failure pattern, buckling capacity, strength and stiffness of specimens were investigated.
