Thin walled steel columns are vulnerable to damage caused by local and overall buckling during an earthquake. This paper presents a Finite-Element Analysis Method to predict the buckling and post-buckling behavior of thin-walled steel box columns. This study is focused on the ductility capacity and buckling strength of thin-walled steel box stub-columns. A three dimensional model of thin-walled steel box column and a buckling analysis of the model is presently being carried out with the aid of the ABAQUS software package. Both initial geometrical imperfections and residual stresses are considered in the shell elements. A geometrically nonlinear load displacement analysis of the structure containing the imperfection is then performed using the Riks method. Analytical results are compared with experiment results in existing literature. The initial stiffness and ultimate strengths of thin-walled steel box columns obtained from the analysis generally fit well with the experimental results. Based on the analysis result, we carried out an analysis to thin-walled steel box stub-columns with longitudinal stiffeners under combined loads.

The analytical studies included nonlinear finite element analysis of split-tee connection details subjected to axial load and lateral load. A three-dimensional model of the connections between CFT columns and H-beams has been developed. Both initial geometrical imperfections and residual stresses are taken into consideration. A geometrically nonlinear load-displacement analysis of the structure containing the imperfection is then performed, using the Riks method. Analytical results are compared with existing experimental results. Extensive parametric analyses are carried out to investigate the relation of the connections between CFT columns and H-beam to various parameters such as the axial load, column width-thickness ratio, and split-tee thickness.
