| In order to calculate the force transmitted to the top of pier induced by high-speed train running through continuous girder bridge, the semi-analytical dynamic interaction model is established for train-track-continuous girder bridge system, in which the dynamic character-istics of train, track, and bridge are taken into account. In the method, all the derivations are carried in the frequency domain and the vibrations in the time domain are obtained by inverse Fourier transformation, which makes it very convenient to observe dynamic characteristics of train-track-bridge structure from the point of frequency. Compared to the FEM model, the presented semi-analytical method is easier to calculate and the solution is more accurate. |
