速度の指数乗に比例して力を発揮する粘性ダンパーを設置した鋼構造建物の等価線形化法による地震応答予測  [in Japanese] SEISMIC RESPONSE PREDICTION FOR STEEL BUILDINGS WITH VISCOUS DAMPERS DEPENDENT ON FRACTIONAL POWER OF VELOCITY BASED ON EQUIVALENT LINEARIZATION TECHNIQUE  [in Japanese]

This paper proposes a general method based on equivalent linearization technique using results of static pushover analysis with three dimensional frame model to predict seismic peak responses of steel structures with viscous dampers dependent on fractional power of velocity subjected to earthquakes. In this method, the equivalent damping coefficient at a given displacement is obtained by averaging damping coefficients of stationary vibration at displacement amplitude up to that displacement level. Time history response analyses were conducted to ensure accuracy of this method.
