摘要
在收集有关拱桥及动力学资料的基础上,基于动力有限单元法理论,以郑州黄河二桥为背景,应用ANSYS有限元软件建立分析模型,深入分析了各参数变化对下承式钢管混凝土拱桥动力特性的影响。
On the basis of existing data collected of arch bridges and dynamics, taking the example of Yellow river Bridge in Zhengzhou, establish finite dement model of it with software ANSYS, analyze the dynamic characteristics of the through type concrete filled steel tube arch brieh under different structure parameters.
