“…In summary, the research on dynamic performance of bridges is mainly concentrated on continuous rigid frame bridges, arch bridges, suspension bridges, cable-stayed bridges and other bridge types [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. But the research on hybrid girder cable-stayed bridge of railway is relatively scarce.…”

Based on the Yongjiang Bridge, this paper used the numerical calculation and the field dynamic load test to study the coupled vibration and dynamic response of the steel box hybrid girder cable-stayed railway bridge. Each vehicle in the train was simulated with 31 degrees of freedom, and the oscillatory differential equation of vehiclebridge coupling was established by MATLAB software. Afterwards, the field tests were also conducted to determine the free vibration characteristics as well as the strain, displacement, and acceleration of the bridge superstructure under trains moving at different speeds and braking at a specified position from a set speed. According to the dynamic load test and Vehicle-Bridge Coupling Vibration analysis, the following conclusions are obtained: (1) The calculated results of vehicle-bridge coupling vibration agreed well with the measured ones, and the program could be used to analyze the dynamic performance of Railway cable-stayed bridges with steel box composite girders. (2) The measured first-order natural frequencies of transverse, vertical and longitudinal vibration were 0,39 Hz; 0,49 Hz and 0,88 Hz, respectively. The dynamic coefficients are 1,04-1,13, the maximum lateral and vertical accelerations are 1,10 m/s 2 and 1,11 m/s 2 , and the maximum derailment coefficient and load reduction rate are 0,55 and 0,39, respectively. These data showed that the dynamic parameters of bridges and vehicles met the requirements and had good stiffness and dynamic performance. (3) This paper, using the frequency limit of simply supported beam to restrain the natural frequencies of cable-stayed bridges is not appropriate, and it is necessary to propose the natural frequency limit value of cable-stayed bridge.

“…Furthermore, more information can be found in [2,3] for high-speed trains in South Korea. Kim et al [4] have summarized most of the railway bridges along the high-speed railway construction in South Korea. Most of these highspeed railway bridges are double-span continuous prestressed reinforced concrete (PSC) box girder bridges with 40 m span, or single-span steel plate girder bridges with 40 m to 50 m span.…”

“…Most of these highspeed railway bridges are double-span continuous prestressed reinforced concrete (PSC) box girder bridges with 40 m span, or single-span steel plate girder bridges with 40 m to 50 m span. The PSC box girder bridges are relatively dominant because there is a general consensus that concrete bridges are superior to steel bridges in terms of vibration and noise [4]. Furthermore, Kim et al [4] have concluded that the dynamic performance of steel and concrete bridges has shown eligible differences for low and medium speeds up to 300 km/h.…”

Yonjung Bridge is a hybrid multispan bridge that is designed to transport high-speed trains (HEMU-430X) with maximum operating speed of 430 km/h. The bridge consists of simply supported prestressed concrete (PSC) and composite steel girders to carry double railway tracks. The structural health monitoring system (SHM) is designed and installed to investigate and assess the performance of the bridge in terms of acceleration and deformation measurements under different speeds of the passing train. The SHM measurements are investigated in both time and frequency domains; in addition, several identification models are examined to assess the performance of the bridge. The drawn conclusions show that the maximum deflection and acceleration of the bridge are within the design limits that are specified by the Korean and European codes. The parameters evaluation of the model identification depicts the quasistatic and dynamic deformations of PSC and steel girders to be different and less correlated when higher speeds of the passing trains are considered. Finally, the variation of the frequency content of the dynamic deformations of the girders is negligible when high speeds are considered.
