摘要

结合某(48+4×80+48)m刚构连续梁桥的工程实例,对长联多跨刚构连续梁桥运用反应谱、时程分析两种分析方法进行了地震响应分析。分析研究了设置液体粘滞阻尼器、设置Lock-up装置两种使用阻尼器的减震方案的减震效果,并对设置阻尼器位置、设置Lock-up装置的位置进行了对比分析。通过分析研究,得出了一些对实际工程抗震设计有借鉴意义的结论。
Taking a(48+4×80+48)m rigid frame-continuous gird bridge as an example,seismic response of a long multi-span rigid frame-continuous girder bridge is analyzed with response spectrum method and time-history analysis method.The affect of the two plans with setting fluid viscous damper and lock-up device to seismic isolation design is analyzed,and the positions of them are compared simultaneously.According to the analysis,some meaningful conclusions to the seismic design of the practical engineering are obtained.
