| 摘 要： | 以郑州市某跨河桥为工程背景,以现行规范为基础,运用有限元软件midas建立模型,结合反应谱法对该桥桥墩进行E1和E2地震作用下的抗震验算。通过桥梁抗震验算可知,满足抗震设防目标,满足规范要求,其方法可为同类桥梁抗震验算提供参考。

| Abstract: | Taking a river-crossing bridge of Zhengzhou as the engineering background,based on the current specifications,a model is established by the finite element software MIDAS.Combined with the response spectrum method,the anti-seismic checking calculation of this bridge pier is carried out under the action of E1 and E2 earthquakes.The result of anti-seismic checking calculation shows that this bridge meets the earthquake fortification target and code requirements.This method can provide the reference for the anti-seismic checking calculation of the similar bridges. |
