This paper presents a theoretical study on the performance of concrete-encased concrete-filled steel tube (CFST) box columns subjected to eccentric axial loading. Finite-element analysis (FEA) was used to analyse the composite columns and experimental data reported recently by the authors was used to verify the FEA modelling. Analysis of the behaviour of the . In the study by Rahman, Begum and Ahsan paper [16], Three different shapes of the structural steel section are used in the specimens i.e., H, cross and I shaped sections, as illustrated in Fig. 1 below, where Fig. 1 (a) is showing a fully encased column FEC with “H” section, Fig. 1 (b) is showing an FEC with two “I” sections, and Fig. 1 (c) is showing am FEC . Concrete-encased columns reinforced with one built-up steel core are widely used as mega columns in high-rise buildings. Due to the enormous size of the steel core, multiple steel segments have to be welded and spliced on-site, which might inflict detrimental impacts on the integrity and ductility of the columns.
