In the previous papers (1), (2), authors treated of the support space-versuse-the rotation capacity relationship of the beam under uniform moment and moment gradient. In this paper, we make clear the rotation capacity, lateral support space, and the behavior of local buckling about the lateral bracing beam on the both sides of plastic hinge. In these experiments we planed two new apparatus in order to experiment the elastic-plastic beam including the experiment, Vid. Fig. 2, Fig. 3). The moval reaction point apparatu showing Fig. 3 is took away faults that the reaction point restrains the deformation at the loading point or the center of loading moves after deformation. (Vid. Fig. 4) In order to examine the propriety of two apparatus we try to experiment the buckling of the elastic-plastic beam. As a result of these experiment we confirm that these two apparatus exhibit the arranged capacity. Then, we try to experiment the plastic design beam using these appartus, and we obtain the following results. i) As a result of the completion of these apparatus, we can experiment with the beam in elastic or plastic range of every kinds. ii) The supports space of bracing beam on the both sides of plastic hinge is property 50 ry.
