  • Dynamic response of high-speed railway bridges is important due to the possibility of resonance from continuous and repeated action of high-speed train running. Acceleration of bridge deck is important parameter in the evaluation of dynamic stability of bridges. This study investigated acceleration characteristics according to type of tracks.

  • In this paper the effect of frequency domain on the estimation of acceleration of high-speed railway bridges was investigated. Field test was conducted for two bridges. One bridge has ballasted tracks, the other slab tracks. Acceleration and displacement were measured. Effect of filtering on acceleration and displacement was analyzed.
