A new type of the K-braced frame with shear resistance member made of ordinary steel (SS400), from a view point of practical use, as a hysteretic damper, is proposed. In order to prevent a rapid deterioration of the hysteresis loop of the shear resistance panel due to plastic shear buckling, the following items are investigated experimentally. 1) the out-of-plane deformation characteristics of the shear panel. 2) the influence and effect of some different stiffenings of the shear panel and annealing the shear resistance member on its energy absorbing capacity. Loading tests of the shear resistance members, which have various kinds of panel stiffeners and with or without annealing, are carried out, and it is clarified that the adequate stiffening the panel using the cut tee panel stiffener and the annealing the shear resistance member lead to obtain its excellent characteristics in plastic deformation and energy absorption capacity as a hysteretic damper.
