摘要
采用有限元法分析了京津城际轨道跨北京四环大桥的整体动力特性。采用反应谱法和时程反应分析法对该桥进行了地震反应分析,以期为进一步研究加劲拱连续梁桥的抗震性能,制定相应的抗震措施提供参考。
The whole dynamic characteristic of the large bridge on Beijing to Tianjin express rail over Beijing No.4 Ring Road is analyzed by finite element method.The seismic response of the bridge is analyzed with response score and time-history analysis.The study provides a theoretical basis for earthquake-resistance of stiffening arch continuous beams.
