Previous researches have been proposed evaluation methods of the maximum moment for pure bending. Moreover evaluation methods of the ultimate load for thick walled square tubes subjected to bending and compression have been established. However evaluation methods of the ultimate load for thin walled square tubes subjected to bending and compression have not been established yet. In this paper, the ultimate load of square tubes subjected to bending and compression are studied by using the finite element method. It is found that there are six types of collapses. Based on these facts, an approximate numerical method to evaluate the ultimate loads for square tubes subjected to bending and compression is proposed, and its validity is verified by comparing with the numerical results by FEM under various conditions.
