Paper Title:
Vertical Load-Carrying Natural Frequency of Railway Double-Track Steel Truss Continuous Bridge
  Abstract

The railway double-track continuous bridge vertical load-carrying frequency is theoretical derived with the vehicle-bridge system mode1. The vertical load-carrying frequencies of the3×64 m through stud welding railway steel truss bridge are calculated, when two trains with 20 same high-speed passenger vehicles are traveling on the bridge from both ends. The change regularity of this double-track continuous bridge vertical load-carrying natural frequency with two trains on it is similar with the single-track simply supported bridge and this bridge vertical load-carrying natural frequency only one train on it. This bridge vertical load-carrying frequency when two train on it is smaller than that only train on it. The maximum deviation percentage between the vertical load-carrying natural frequency and the vertical natural frequency is 6.0452%. The vertical load-carrying frequency can be replaced by the average value.
