近断层地震方向脉冲效应对高速铁路桥梁弹塑性反应的影响

Effect of Near-fault Seismic Effect on Direction of Pulse Response of Highspeed Railway Bridge Elastoplastic

根据PEER-NAG强震数据库资料通过采用ANSYS软件进行分析,根据高速铁路多跨剪支桥作为研究的对象,从而能够建立起近断层脉冲型地震的高速铁路桥梁安全模型,与此同时也需要对轨道不平顺的影响以及结构自震的特性进行分析。在本文中,主要是对近断层地震方向脉冲效应对于高速铁路桥梁工程的弹塑性反应影响作出了全面的分析研究,并且在这个基础之上提出了下文中的一些内容,希望能够给与同行业人员提供参考。

By using ANSYS software to analyze, according to the high-speed railway multi span shear supported bridge as the object of study, so as to set up near fault pulse type earthquake of high speed railway bridge security model, at the same time also need to track irregularity along the effects of self vibration characteristics were analyzed. In this paper, mainly of near fault earthquake direction impulsive effect for high speed railway bridge engineering elastic plastic influence the reactivity of the made a comprehensive analysis and research, and on this basis to put forward the following some of the content, hope to be able to give the same industry personnel to nrovide the reference.
