“…The program was originally developed by the authors and its validity and reliability had been confirmed in the past researches [11][12][13]. In order to further verify whether the calculation results by this program of the vehicle-bridge coupled vibration analysis are correct, it is used to calculate the coupled vibration response of a double-DOFs vehicle model and a simply supported beam bridge model shown in Fig.…”

“…Korti et al [10] used a simple bridge model to analyze the effect of the spatial vehicle model on the bridge vibration response in comparison with that of the plane vehicle model. He et al [11][12][13] developed a 3D numerical procedure on vehicle or train-bridge coupled vibration system, which is applied to solve various problems such as traffic-induced environmental vibration, seismic response of train-bridge interaction system, and curved girder bridge vibration response under vehicle loads, etc. However, there were few researches focusing on the running vehicle-induced vibration problem of concrete-filled steel tube arch bridges constructed in the past, especially considering accurate vehicle-bridge coupled vibration with sophisticated vehicle and bridge dynamic models and complicated real conditions.…”

To numerically evaluate the reinforcement effect on dynamic characteristics of a concrete-filled steel tube arch bridge with vibration problems, a 12-degree-of-freedom sprung-mass dynamic vehicle model and a 3D finite element bridge model were established. Then, the coupled equations of vehicle-bridge interaction were derived and a computer program was developed using the FORTRAN language. This program can accurately simulate vehicle-bridge coupled vibration considering the bumping effect and road surface irregularity during motion of the vehicle. The simulated results were compared with those of relevant literatures to verify the correctness of the self-developed program. Then, three reinforcement schemes for the bridge (Addition of longitudinal beams, Reinforcement of bridge decks, and Replacement of suspenders) were proposed and numerically simulated, and the vibration reduction effects of the three schemes were evaluated based on the numerical results to find effective ones. It is confirmed that the reinforcement scheme of Addition of longitudinal beams shows the most significant vibration reduction effect. It is recommended in the engineering practice that the combination of the reinforcement schemes of Addition of longitudinal beams and Replacement of bridge deck can be used to solve the excessive vibration problem.
