“…The study simulates the bridge with the finite element method and models the vehicle as a multibody assembly. The proposed analysis scheme derives from a previous work of Dimitrakopoulos and Zeng (2015), on vehicle-bridge interaction between trains and (horizontally) curved bridges, with the following changes: (1) the interaction model herein follows a different approach and results in modified equations of motion for the VBI system (compared to Dimitrakopoulos and Zeng 2015). Specifically, it calculates the contact forces based on the compliance of the tires and accounts for (the potential) detachment of the wheels from the deck.…”

Traditionally, the seismic response analysis of a bridge does not account for the concurrent vehicle-bridge dynamic interaction. However, the behavior of a seismically excited bridge can jeopardize the safety of the vehicles running on it, even if the bridge itself remains undamaged. This study examines the seismic response of a vehicle-bridge interacting (VBI) system under vertical earthquake excitation, modelling the truck vehicles as rigid body assemblies. An application of the proposed scheme to a realistic case of (highway) bridge-(truck) vehicles shows that the earthquake ground motion and the road surface conditions are the main sources of excitation. The results show that the road surface conditions influence strongly the dynamics of the VBI system, even when the vertical component of the earthquake excitation is significant. Also, the study brings forward the influence of traffic parameters (namely the speed, the number and the distance between the running vehicles) and underlines the need to consider different positions of the vehicle/s (on the deck) during the earthquake shaking. Finally, it examines the tendency of the wheels of a truck vehicle to detach (jump) from the deck during the seismic response of the VBI system. Detachment tends to be more frequent as the road surface conditions deteriorate and/or the peak ground acceleration increases. However, detachment is a complicated phenomenon which depends also on many other ground motion and VBI system parameters and deserves further study.

Abstract. This paper takes a four span continuous curved box girder bridge as an example. The bridge calculation model was established by finite element software ABAQUS. The calculated data is compared with the field test data to verify the model. Then the dynamic response of the bridge under different moving loads is studied. And the influence of the lateral position of the truck, axle load and centrifugal force on dynamic response of the curved bridge are analyzed. The results show that torsional effects of bridge due to eccentric loading has great influence on the curved bridge dynamic responses, and the centrifugal force obviously increases the section torque. In the elastic range, the midspan deflection and the support reaction all increase linearly with the increase of the load.

“…There are numerous publications regarding the dynamic analysis of train-bridge interactions [1][2][3][4][5]. Some of them focused on the effect of trains on the natural frequencies of bridges due to the effects of carriage masses coupled with the bridges through suspension systems, namely railway bridge on-load natural frequency.…”

Abstract. Based on Cellular automation (CA) traffic flow simulation technology widely used in the transportation field, a general framework of investigating the variation of natural frequencies of a roadway bridge under vehicle flow was developed. The results revealed that the values of the frequencies decrease as the traffic density increases and the effect on high modes of the bridge under vehicle flow is more significant.
