A large number of bridges were built several decades ago, many of which have suffered serious deterioration or damage due to the increasing traffic loads, environmental effects, material aging, and inadequate maintenance, and thus, the stiffness of these bridge structures is generally small, the vibrations can be easily excited by any external loads such as moving vehicle loads and/or wind loads. Based on the vehicle-bridge coupled vibration, the 3-D vehicle model which can consider the effect of the patch contact on the dynamic response of the bridge-vehicle coupling system, dynamic behavior of the damaged bridge with multiple cracks, the pavement effect on the coupled vibration, the nonstationary and stationary vibrations of a bridge-vehicle system with a variable vehicle speed, and the lateral and longitudinal vibrations of bridges induced by the moving vehicular loads are presented.
