DYNAMIC ANALYSIS OF A COUPLED HIGH-SPEED TRAIN AND BRIDGE SYSTEM SUBJECTED TO SEA WAVE HYDRODYNAMIC LOAD

In this study, the dynamic behavior of 3D train-bridge system subjected to different hydrodynamic loads (TBW model) is established. By taking a continuous bridge with box girders as case responses which under train passing and several sea are analyzed. Hydrodynamic forces applied on piers according Morison’s theory car body modeled by 27-DoFs system. Model validation has been performed other research considering vessel collision load. continuation, running safety indices conditions Consequently an assessment procedure proposed for high-speed trains bridges wave loads. Results TBW’s sensitive analyzes have shown importance sea-states safe comfortable running. These outputs indicates that in stormy conditions, speed crossing should be reduced it possible pass at low speeds conditions.
