银滩黄河大桥独塔斜拉桥动力分析

Dynamic Analysis of the Single Pylon Cable-stayed Yintan Bridge over Yellow River

对银滩黄河大桥桥塔和主梁间纵、横弹性约束对主桥的动力特性、地震反应影响作较全面的计算分析。内容包括动力计算模式的建立、动力特性计算及地震反应分析。计算结果表明 ,银滩黄河大桥主桥所采用的运营时主梁弹性约束。

An overall computation and analysis was made of the pylon, and the impact of main girder longitudinal and transverse elastic confinement on the dynamic property and earthquake response of the main bridge, including establishment of computation model, computation of dynamic property, and analysis of earthquake response. Computation result indicated that elastic confinement for operation and the float system for earthquake have high aseismic performance.
