“…3 refer to, respectively, as the bridge midspan and total displacement response to three vehicle's constant speeds, 3 m/s, 10 m/s, and 30 m/s. Using different vehicle velocities with the lowest and highest amount has been adopted in previous research, e.g., Bencat [25] and Refs [15,16], to accurately study the various bridge dynamic behavior. As shown in Fig.…”

“…Although many works have been carried out to analyze the dynamic interaction, especially the frequency response [12][13][14], engineers and researchers should notice the effect of high vehicle speed on the bridge deflection. To substantiate this issue, José [15] investigated and concluded that the maximum dynamic increment factor for a bridge subjected to a highspeed train appears at a critical speed. According to José's research, the displacement and the torsional rotation of the bridge deck at the center of span 11 of Arroyo de las Piedras viaduct in Córdoba-Málaga HS line were obtained using the Rayleigh method by considering critical train speed of 350 km/h.…”

Several authors, utilizing both experimental tests and complicated numerical models, have investigated vehicle speed's impact on a highway bridge's dynamic amplification. Although these tests and models provide reliable quantitative data on frequency contents of the interaction between the two subsystems, engineers should pay further notice to the effects of a subsystem's velocity and the type of suspension system of a vehicle moving over a structure. Hence, in this paper, the dynamic response of a bridge to a moving vehicle is considered. The car is assumed as a quarter car model with both linear and nonlinear stiffness and damping constants. Further, using the modal superposition method, a closed-form solution is obtained for the bridge's vertical response. The results obtained via numerical calculation show a significant increase in the bridge midpoint and total deflection, velocity, and acceleration by increasing the vehicle velocity. Moreover, by neglecting the nonlinear stiffness and damping coefficients of the vehicle suspension system, the bridge's dynamic response remains almost the same with respect to the numerical data. As a general conclusion, it can be claimed that the only significant parameters which can change the dynamic behavior of a bridge subjected to a moving vehicle are the speed of the car and its linear stiffness and damping constants inside its suspension system.

“…Reasons for that are the reduction of travel times, better interoperability, and eco-friendliness of railway transport against road transport [2][3][4]. When referring to HS lines, the commercial speed is typically higher than 200 km/h, which has been proven to produce appreciable dynamic effects on bridges, thus raising concerns of eventual resonance [5][6][7][8][9]. Therefore, structural design codes for HS viaducts have established that dynamic analysis must be performed at the design stage in order to ensure structural safety and users' comfort [10,11].…”

It is known that short-span high-speed railway viaducts are prone to suffer significant dynamic effects due to the passage of moving train loads. Recent technological advances in railway engineering have resulted in track typologies different from the conventional ballasted track consisting of discrete sleepers fastened to the rails and resting on a ballast bed. In particular, ballastless track has been identified as an effective solution due to reduced maintenance costs, high track stability and excellent geometric quality. Though different track typologies are available in the market, they can be classified as monolithic or independent according to the interaction degree with the bridge girder. In the present paper, the dynamic behaviour of short-span bridges is numerically studied by taking into account the track-bridge interaction by modelling explicitly the components of the track. Two types of ballastless track (monolithic continuous slab and independent short slabs) and conventional ballasted track are considered on simply supported bridges with span length in the range of 15-25 m subjected to envelope and commercial train loads at speeds between 200 and 360 km/h. In total, 2448 numerical cases have been analyzed. The study shows that dynamic deflections and accelerations produced at the bridge girder by moving train loads can be reduced when the ballasted track is replaced to ballastless track systems, especially for the critical speeds higher than 300 km/h. Moreover, it is shown that the two ballastless track systems lead to very similar results, with the monolithic system resulting in slightly smaller bridge deflections and also moderately larger accelerations.
