【摘要】 研究了设有粘弹性阻尼器的连续梁桥的地震反应,探讨了阻尼器在连续梁桥中的减震效果及阻尼器参数对减震效果的影响。结果表明:阻尼器对桥梁结构具有减震效果,要达到良好的减震效果必须对阻尼器的参数加以优化。更多还原

【Abstract】 Abtract:The seismic response time-history of a continuous girder bridge with viscoelastic damper is ana-lyzed.The effect of vibration mitigation of the damper in bridge and the influence of the damper parame-ters to the absorption effect are discussed.The result shows that the bridge with viscoelastic damper canminimize seismic response,and the damper parameter should be optimized in order to get nicer effect.更多还原
