| Abstract: | In essence, vibration of bridge caused by vehicle is coupled vibration of two dynamic systems of vehicle-bridge. The author computes the vehicle-bridge vibrations of the common simply supported-continuous box beam bridges and analyses the dynamic capability resulted from bridge deck pavement and the change of cross-sections size and vehicle velocity. The paper finds out the main factors that affect the dynamic capability of bridge, and gives some advice about the design of this kind of bridge. |
