In the previous paper, the authors proposed a method of analyzing the strength of framed structures by means of elastic-plastic hinge method to save the computing time and simplify the analysis. The equivalent moment versus rotational angle relationship of an elastic-plastic hinge is obtained by elastic-plastic beam theory applied to the part between elastic-plastic hinges. In this paper, generalized elastic-plastic hinge method taking into account of the effects of shearing force and the round corners of deep web frames superposing to the effects of the bending and axial force is developed, showing several examples of its applications. And it is shown that the elastic-plastic failure loads and load〜deflection curves obtained by this method are practically agreed well with the values obtained by Nitta's experiments.
