ANALYSIS OF LOADED DYNAMIC CHARACTERISTICS OF SIMPLY SUPPORTED BEAM BRIDGES ON HIGH SPEED RAILWAY

    Graphical Abstract
    • Abstract
  • In this paper, the formula to calculate the natural frequencies of vertically loaded simply supported beam railway bridges is developed based on the vehicle-bridge system model. A simple and convenient algorithm is introduced. Besides, the free frequencies for the vertically loaded simply supported beam bridges with different spans are investigated.
