Experimental and theoretical study has been carried out to investigate the stability and post-buckling behavior of concrete filled steel square tubular columns. An extensive experimental program which included thirty columns, twenty four of them were filled with concrete, of different effective length-section depth ratios and several eccentric loads, has been done. A computer program for predicting the ultimate load, and the relation between the load and the corresponding lateral displacement, has been developed and checked against the experimental results. Also, a new model has been proposed to predict the post-buckling behavior and good results have been obtained. Strength formulae of AIJ for concrete filled steel tubular columns were investigated by comparing with the test results, and it has been shown the design formulae for long columns are so conservative.
