| Abstract: | 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. |
