| Abstract: | The seismic reduction performance of high pier and long span railway simply-supported steel truss girders with the bearing of shock absorption and vibration isolation is presented by using time history response analysis,and technical applicability of shock absorption and vibration isolation for the bridge of high pier is discussed.The seismic reduction effect of lead rubber bearing,pot rubber bearing and hyperbolical bearing is researched by using numerical analysis.The calculated result shows that some seismic reduction effects is obtained by using the bearing of shock absorption and vibration isolation on the high pier and long span railway simply-supported steel truss girders. |
