| 摘 要： | 异型拱桥的地震反应不同于常规拱桥,具有明显的空间耦合效应,利用有限元理论对张家口通泰大桥的空间抗震性能进行了研究,着重分析了纵向、竖向和横向三向地震波传播效应对该桥地震反应峰值的影响,为该类型桥梁的抗震分析提供了一定的参考依据。研究结果表明,在纵向、竖向行波效应下,结构控制截面的内力均有明显的变化,横向行波效应下结构控制截面内力变化较小,但内力的峰值明显要比纵向、竖向输入产生的结果要大。

| Abstract: | The seismic response of special-shaped arch bridge was different from conventional arch bridge with obviously spatial coupling effect,it was researched the spatial seismic behavior of Tongtai Bridge in Zhangjiakou by finite element theory,and was analyzed the effect of seismic response peak on this bridge under propagation of longitudinal,horizontal and vertical seismic waves,which provided a reference for seismic analysis of this type bridge.The results showed that in the longitudinal,vertical traveling wa... |
