摘要
在桥梁设计中,自振频率、振型对评价桥梁现有运营情况和承载能力有重要的意义。利用大型有限元计算软件Ansys,通过对某在建高速铁路单箱双室组合梁进行数值计算,分析了横隔板的设置对桥梁动力性能的影响。
In bridge design, natural frequency of vibration and mode of vibration have important meanings in evaluation on existing operation and bearing capacity of bridge. Through the utilization of large - size finite element calculation software Ansys and numerical calculation on single - box double - room composite beam of a high - speed railway under construction, the influence of installation of diaphragm plate on dynamic performance of bridge is analyzed.
