“…Walker et al 14 , and Crockett and Pyke 15 used the FE method to calculate the vibration of bridges, but they just made a simple estimate of structure-borne noise based on the derived vibration of each bridge component. The direct use of the FE and BE methods in noise predictions was adopted by Zhang et al 16 and Wu and Liu 17 . Li et al 18 utilized the mode superposition method in a three-dimensional (3D) FE analysis to calculate the dynamic responses of the train-trackbridge system and used the modal acoustic vector in a 3D BE analysis for the prediction of low frequency bridge noise.…”

“…Janssens and Thompson 6 applied a model of two infinite Euler-Bernoulli beams connected by a single resilient layer, developed by Pinnington 25 , to calculate the power transmitted to the bridge from the rail excited by a point force. For the prediction of low frequency noise from the bridge, Li et al 18,19 , Zhang et al 13,16 and Song et al 20 utilized a discrete spring model for the direct fastening system between the rail and bridge to obtain the vibration of bridge induced by the moving trains. The stiffness of the fastening system was assumed to be constant for frequencies below 250 Hz.…”

Concrete viaducts are an important part of the urban rail transit system but they produce considerable noise pollution in the communities nearby. The vibration generated at the wheel-rail interface is transmitted along the rail and also into the bridge so that noise is radiated from both the rail and the bridge. To facilitate noise predictions it is desirable to develop a model that takes into account the vibration generation and transmission in the traintrack-bridge system. The vibration and the associated noise of the track-bridge system are computed with a unified vibro-acoustic model using a wavenumber domain finite element and boundary element method. An important aspect is shown to be the frequency-dependent stiffness of a typical rail fastener utilized on bridges due to resonance of the baseplate between two rubber pads. In this study a multi-layer fastener model is proposed to allow for this effect. The proposed procedure is applied to a viaduct with a U-shaped section and compared with field measurements during train pass-bys. The elastic modulus and damping of the rubber pads and equivalent loss factor of the rail are chosen by fitting the calculated track decay rates to those estimated from measured rail accelerations under train passages. The wheel-rail combined roughness is also derived from the measured rail vibration. A comparison is then made between the simulated and measured bridge vibration to verify the proposed method as well as the parameters used in the track-bridge system. The predicted noise levels are also compared with the measured results. The effects of the fastener model, fastener stiffness, bridge damping and interference between multiple wheels are then discussed. It is found that the bridge noise has a non-negligible effect on the total A-weighted noise levels in the region beneath the bridge and up to 30 m away from the track.

“…The adoption of new thin-walled U-shaped concrete girders in urban rail transit systems in Shanghai led to more noise complaints than the traditional box girders, prompting Wu and Liu [7] and the authors [8,9] to investigate this problem. Low-frequency noise from concrete bridges has been recently investigated by Li et al [8], Kozuma and Nagakura [10], and Zhang et al [11,12], who applied a three-dimensional (3D) boundary element method (BEM), and by Li et al [9], who used a two-and-a-half dimensional (2.5D) BEM-based procedure. To tackle vibro-acoustical problems in the mid-frequency range for general systems, hybrid methods using the finite element method (FEM) and SEA were proposed by Cotoni et al [13] and Maksimov and Tanner [14].…”

“…Zhang et al [39,40] proposed the hybrid FEM-BEM method for calculation of box girder noise. A bridge's dynamic response in the time domain can be obtained through solution of the FEM for train-track-bridge coupled vibration; it could then be transferred into the frequency domain via fast Fourier transform.…”

In recent years, there has been rapid growth of Chinese rail transit networks. Many of these networks require elevated bridges. This results in a bridge-borne noise source, which occurs in addition to the main noise source (i.e., wheel-rail interactions). Bridge-borne noise is attracting increasing attention because of its low-frequency noise characteristics. This review paper first analyzes the space distribution, spectral characteristics, and sound pressure levels of noise radiated by all-concrete, steelconcrete composite, and all-steel bridges, mainly according to experimental studies. Second, this paper reviews existing theoretical prediction models of noise emanating from bridges: the semianalytical method, the Rayleigh integral method, the boundary element method, and statistical energy analysis. Several case studies are reviewed, and their results are discussed. Finally, according to the results of the current review, the main factors affecting bridgeborne noise are analyzed, several noise reduction measures are proposed for different types of bridges, and their effectiveness is demonstrated.
