The behavior of centrically loaded box-section steel columns until they have reached a stage of complete collapse was studied by carrying out a series of experiments and analyses. The results obtained from this study can be summarized as follows: (1) The behavior after the yield of the steel columns can be divided into two types; the flexural buckling type in which the progress of lateral deflection results in collapse and the local buckling type in which the local buckling occurring successively along member-length results in collapse. A conditional expression of members for the discrimination of these two types of behavior was derived. (2) A method for analyzing the behavior of flexural buckling type members was developed and the validity of this analysis method was confirmed in comparison with the experiment results. (3) A model to estimate the load-deflection relationship of local buckling type members was derived.
