The input ground motions with permanent displacements due to the thrust fault with the Japan Meteorological Agency Magnitude M6.5, subjected touch supports of the bridge, are simulated using the stiffiness matrix method where the kinematic source model and the horizontaly layered half space are assumed. The steel truss bridge is modeled as the three dimensional nonlinear frames using the Fiber Element Method. The effects of the sedimentary layer and the depth of the upper edge of the fault upon the ground motions, and upon the behavior of inelastic response of the steel truss bridge are examined. It is found that the vertical ground motions are distinguished and they significantly affect on the inelastic response behavior of the steel truss bridge. It is also found that the thickness of sedinlentary layer as well as the spatial position of the bridge strongly affect on the response behavior of the bridge.}, pages = {454--466}, title = {逆断層近傍における上路式鋼トラス橋の応答特性}, volume = {57A}, year = {2011}, yomi = {コダマ, ヨシヒデ and ハラダ, タカノリ and ノナカ, テツヤ and ナカムラ, マサキ and ウサミ, ツトム and コダマ, ヨシヒデ and ウサミ, ツトム} }
