| Abstract: | The natural vibration property of a concrete continuous beam-arch composite bridge with 76+160+76 m span on Guang-Shen-Gang high-speed railway is analyzed using 3D finite element model.The influence of lateral brace stiffness and arch lib section on the natural vibration property of the bridge is also studied.Dynamic properties of the bridge,running safety of train and the riding comfort of passengers are assessed in detail.Some useful results are gotten.It is beneficial for the design of this type of bridg... |
