“…In 2003, to investigate the dynamic responses of the Antoing Bridge located on the high-speed railway line between Paris and Brussels subjected to Thalys trains, Xia et al performed a test by measuring the modal parameters, deflection, acceleration, strain of girder concrete and so on, which can be a reference for the study and the design of highspeed railway bridge [119]. During the next 15 years, plenty of research conducted by Shin et al [120], Guo et al [121], Wang et al [122] and so on, played an important role in assessing the running safety and ride comfort of the train-track-bridge dynamic system. The authors also have done many remarkable works in this field, one of which is illustrated for instance.…”

“…The numerical simulation of the train-track-bridge system under the wind excitation have been applied to assess high-speed railway bridges crossing large river or valley [96,97], to investigate the influence of turbulent winds on the running safety of the train on a bridge and obtained the threshold curve of wind velocity and train speed [178,179], and to evaluate the improvement of the dynamic performance of the system with the wind barrier [121,175,180,181] or TMDs [180] installed on the bridge for achieving an optimal design of vibration control measure under the wind excitation.…”

Train-track-bridge dynamic interaction is a fundamental concern in the field of railway engineering, which plays an extremely important role in the optimal design of railway bridges, especially in high-speed railways and heavy-haul railways. This paper systematically presents a state-of-the-art review of train-track-bridge dynamic interaction. The evolution process of train-bridge dynamic interaction model is described briefly, from the simplest moving constant force model to the sophisticated train-track-bridge dynamic interaction model (TTBDIM). The modelling methodology of the key elements in the TTBDIM is systematically reviewed, including the train, the track, the bridge, the wheel-rail contact, the track-bridge interaction, the system excitation and the solution algorithm. The significance of detailed track modelling in the whole system is highlighted. The experimental research and filed test focusing on modelling validation, safety assessment and long-term performance investigation of the train-track-bridge system are briefly presented. The practical applications of train-track-bridge dynamic interaction theory are comprehensively discussed in terms of the system dynamic performance evaluation, the system safety assessment and train-induced environmental vibration and noise prediction. The guidance is provided on further improvement of the train-track-bridge dynamic interaction model and the challenging research topics in the future. ARTICLE HISTORY

Reduction in weight adjoined with the increase in the railway vehicle speed of travel added to the deteriorating effects of the crosswinds on the running behavior of high speed trains. During the past decade, many researchers have concentrated on examining the aerodynamic force and moment coefficients for the trains. Varieties of studies regarding the effects of crosswinds on the trains are accomplished. However, the need to restrain strong winds from disturbing trains running safety is not completed. This research is concerned with finding a proper solution for attenuating the worrying effects of the winds that hit the trains. Installation of air fences on the sides of the railway tracks is investigated. To serve the purpose, a variety of air fences with different heights, with and without the edges on top of the fences, at a variety of the edge lengths and angles are studied. The study covers double routed railway track while the air fences are installed on either side of the track. The train can be on the leeward or windward line. The problem solving is based on the Lattice-Boltzmann method. This research pioneers in using this method for the said purpose. It is found that by inserting the fences and increasing their heights for up to 1m, the drag forces decrease to 40 percent and the rolling moment coefficients decrease to 15 percent. The presence of the edge can also decrease the drag force for about 55 to 120 percent and decrease the rolling moment coefficients for about 30 to 115 percent in some cases. Variations in percentages of reduction are due to the different angles and the lengths of the edges.

“…Han [5,6] made an accurate identification of the aerodynamic characteristics of vehicles and bridge at the premise of the coupled vibration analysis with a wind-vehicle-bridge system. Guo [7] found that the side force and rolling moment coefficients of the vehicle were efficiently reduced by a single-side wind barrier, but for the bridge deck these values were increased. Prud'homme [8] studied the influence between the sway movement and motion axis on flutter and vortex induced vibration in a 3 DOF wind tunnel test.…”

Aerodynamic admittance is a key parameter affecting the analysis accuracy of the bridge buffeting response. However, few articles have covered the issue of the wide-body flat box girder with much smaller depth-width ratio (such as 1/12 studied in this paper). Therefore, to explore the real buffeting force of the wide-body flat box girder, experiments of the static force coefficients and aerodynamic admittance are carried out in wind tunnel. Wooden segmental model has a scale ratio of 1/60 to an actual 42 m wide suspension bridge girder. Using the high-frequency-force-balance (HFFB) equipment fixed with the segmental model under the conditions of different wind speeds and different wind attack angles, wind power spectrums of the buffeting force are measured and the variation of aerodynamic admittance parameters is analyzed. The results show that the aerodynamic admittance of the box girder measured in the experiment with this so much smaller depth-width ratio differs from the corresponding classical Sears expression. Some inspiration can be presented for the future study of the buffeting response for this kind of much wider bridge with the similar ratio in this paper.
