Abstract
In the present paper, the collapse behaviors of rectangular lubes subjected to pure bending arc investigated using the finite element method. Such bending collapse has been investigated extensively. These studies have revealed the existence of two types of collapse. The first type is a collapse due to buckling at the compression flange, and the second type is a collapse due to plastic yielding at the flanges. Moreover, another type of collapse exists. For a rectangular tube in which the web is wider than the flange, collapse due to buckling occurs at the compression web. In the present paper, previous evaluation method of the maximum moment is refined, and systemized evaluation method is proposed. The validity of this method is verified through comparison with the numerical results obtained by FEM under various conditions.
