【摘要】 以郑州市郑东新区北三环跨东运河桥为工程背景,对该斜拉桥进行了使用摩擦摆支座加阻尼器的减隔震设计,并使用有限元软件对桥梁进行了E1和E2两阶段的非线性时程分析。利用桥梁整体抗震分析计算结果,对桥塔、墩柱及桩基使用UCfyber工具进行了构件抗震验算,得到了一些有意义的结论,可为同类桥梁的抗震设计与计算提供借鉴与参考。更多还原

【Abstract】 With a research background of the north third-ring crossing East Canal Bridge in Zhengdong New Area of Zhengzhou, the combination design of friction pendulum bearing and damper is implemented for this cable-stayed bridge, and the non-linear time-history analysis of the two situations, E1 and E2, are made by use of special FEA software. Utilizing the whole structure analysis outcomes, seismic resistance calculations are made for the bridge tower, the columns and the pile foundations by the tool of UCfyber. Some meaningful conclusions may provide guidance and reference for the anti-seismic design and calculation of other similar bridges.更多还原
