【摘要】 在罕遇地震作用下,只通过设置隔震支座,不能有效改善中小跨径梁式桥的抗震性能。在这种情形下,研究中小跨径高墩梁式桥设置黏滞阻尼器的地震响应就成为桥梁抗震设计的需要。论文以云南9度地震区,地震动峰值加速度0.4g场地为背景,以5跨30m梁式桥为对象,研究分析调整黏滞阻尼器参数引起地震响应的敏感性,供类似桥梁抗震设计时参考。更多还原

【Abstract】 In under the action of the rarely met earthquake,only by setting isolation bearings,can’t effectively improve the small and medium-sized span beam type bridge seismic performance.In this case,research the small and medium-sized span high piers of beam bridge type set viscous dampers of seismic response of the became the need of aseismic design.This paper to yunnan nine degrees in quake zone,seismic peak acceleration 0.4 g site as a background,based on the 5 span 30 m beam bridge type as the object,the research analysis adjustment viscous damper parameters cause seismic response of sensitivity,for similar bridge seismic reference when design.更多还原
