A theoretical study on the ultimate strength of thin-walled box stub-columns subjected to compression and bending is performed by using a finite element method (F. E. M.) on the basis of the elasto-plastic large deflection theory in order to develop an interaction curve at the ultimate state. A modified column method to calculate the ultimate strength of thin-walled box columns considering the local bucking of Plate elements is proposed by using the interaction curve of stub-column. Through numerous calculations by the modified column method, an approximate formula for predicting the ultimate strength of thin-walled box columns is given in this paper.
