Abstract

The use of concrete-filled steel tubes in civil construction offers significant advantages, such as increased strength, ductility, and energy absorption, compared to steel or reinforced concrete columns. This study aims to investigate the compressive behavior of concrete-filled rectangular composite columns. A finite element model was developed and validated using ABAQUS software. It was observed that parameters such as length and thickness of the tube, cross-sectional area, and concrete strength influence the resistance capacity. The results of the numerical models were compared with analytical models to verify the ultimate load. It was found that the normative models were conservative in predicting the resistance capacity of concrete-filled rectangular composite columns.
