dc.description.abstract	A concrete-filled steel tube-reinforced concrete-filled stainless steel tubular (CFST-CFSST) column is a type of CFST column reinforced with an embedded steel profile. Wang et al. [1] at first systematically investigated the inner carbon steel tube reinforced square CFST column. This study employs a non-linear finite element analysis using ABAQUS CAE 6.14 to predict the behavior of CFST-CFSST columns. Six specimens were modeled and subjected to axial compression tests to validate the models against experimental results provided by Wang et al [1]. Key parameters such as ultimate axial strengths, axial load-strain curves, and deformation patterns were compared to ensure the accuracy of the models. Extensive parametric studies were conducted to investigate the effects of various geometric and material parameters, including diameter-to-thickness ratio, concrete compressive strengths, and steel yield strengths on the strength and ductility of CFST-CFSST columns. Finally, this study also examined the deformation and damage patterns of the modeled columns, which closely matched those of the tested specimens. This validation underscores the effectiveness of the numerical models in accurately predicting the structural behavior of CFST-CFSST columns under axial loading. This thesis contributes valuable insights into the structural behavior of CFST-CFSST columns and provides practical recommendations for their design and application in modern construction projects	en_US
