Abstract

Abstract: The dampe is one of the bridge and structuresimportant dynamic-parameters .The study of the influence of damp on bridges helps the seismic resistance design .With the help of shake table tests , this paper presents the effects of damp on the beams and piersseismic behavior .Test results show that the dampe plays key roles in seismic resistance . Properly increasing the structurels dampe value can lowers the amplitude of beams or piers , disturbs the regular phase in vibration and therefore can gain considerable seismic resistance effects

Key words: model , dampe , seismic resistance , phase

摘要： 阻尼是桥梁的重要动力参数之一，研究阻尼在减震中的作用对抗震设计很有指导价值。通过有机玻璃连续梁桥模型振动台试验，分析了阻尼对模型桥梁和墩减震性能的影响。试验表明，阻尼的大小对减震性能有着重要的作用。适当的增加阻尼会降低振动幅值，扰乱振动过程中规则的相位，从而得到良好的减震效果
