Critical parameters that control the earthquake response of steel frames are characterized and incorporated into the equivalent SDOF representation. Maximum and cumulative plastic rotations induced into beam-ends are derived in explicit forms as functions of these parameters, and accuracy of the estimated rotations is demonstrated through the comparison with numerical results.}, pages = {121--128}, title = {梁降伏型鋼構造ラーメン部材の必要塑性変形性能に関する研究}, volume = {537}, year = {2000}, yomi = {オガワ, コウジ and オガワ, コウジ} }
