“…In both contributions the ground response is calculated by applying reaction forces on a 3D FEM with artificial viscous boundaries. Takemiya and Bian [23] investigate numerically the waves generated in the soil near a Japanese Shinkansen multi-span viaduct. The authors also present field tests measurements on the foundations and in the ground far field, showing frequency contents related to train axle distances and structure natural periods.…”

Railway induced vibrations on short-to-medium span simply-supported (SS) bridges is addressed in this contribution. Such structures may experience high levels of vertical acceleration at the platform, leading to adverse consequences such as a premature degradation of the ballast layer and passenger discomfort. In the present study, the evolution of the bridge dynamic response when soil-structure interaction (SSI) is taken into account is investigated. To this end a coupled three-dimensional (3D) Boundary Element-Finite Element model (BEM-FEM) formulated in the time domain is implemented to reproduce the soil and structural behaviour, respectively. First, a set of soil-bridge systems of interest is defined, covering a wide range of lengths and natural frequencies for the structures, and an interval of expectable elastic properties and damping levels for the soil. Then, different types of analyses are performed on the soil-bridge systems extracting conclusions regarding the effect of including SSI in numerical models for predicting the bridge behaviour under railway traffic. In particular natural frequencies and modal damping levels are identified, and the structure amplification after the passage of a moving load in free vibration is investigated. Conclusions regarding how resonance and cancellation conditions may be affected by soil properties are extracted. Finally, the dynamic response of a real bridge, belonging to the Spanish railway network, is evaluated under the circulation of trains that induce second and third resonances of the bridge fundamental mode. The effect of the soil flexibility, soil material damping and the bridge resonance order are evaluated. Conclusions regarding the appropriateness of the results provided by common models which do not include SSI effects are extracted.

“…A number of projects dedicated to the development of future high-speed transportation, used existing highspeed and underground trains like the high-speed Swedish X-2000 train at Ledsgard (Takemiya, 2002(Takemiya, , 2003, the Bakerloo line of London Underground (Degrande et al, 2006b), the high-speed Shinkansen railway in Japan (Takemiya and Bian, 2006) or the Paris metro network (Clouteau et al, 2004) for the development of new measurement techniques and comprehensive finite element -boundary element models (Degrande et al, 2006a;Forrest and Hunt, 2006a,b;Gupta et al, 2006;Chebli et al, 2007;Hussein and Hunt, 2007) correlated to the actual ground structures in order to bring more insight into the propagation of the traffic and ground induced vibrations, tunnel-soil interactions and the development of efficient measures for vibration reduction.…”

The paper analyses theoretically the surface vibration induced by a point load moving uniformly along a infinitely long beam embedded in a two-dimensional viscoelastic layer. The beam is placed parallel to the traction-free surface and the layer under the beam is assumed to be a half space. The response due to a harmonically varying load is investigated for different load frequencies. The influence of the layer damping and moving load speed on the level of vibrations at the surface is analysed and analytical closed form solutions in the integral form for the displacement amplitude and the amplitude spectra are derived. Approximate displacement values depending on Young's modulus and mass density of layers are obtained. The mathematical model is described by the Euler-Bernoulli beam equation, Navier's elastodynamic equation of motion for the elastic medium and appropriate boundary and continuity conditions. A special approximation method based on the wavelet theory is used for calculation of the displacements at the surface.

“…Takemiya and Bian [13] and Takemiya [14] studied the soil-foundation-bridge interaction under moving loads using the substructure method in the frequency domain. They concluded that, in addition to train load profile, bridge geometry and soil properties, soil-structure interaction is crucial for determining the bridge and ground response.…”

This paper explores dynamic soil-bridge interaction in high speed railway lines. The analysis was conducted using a general and fully three-dimensional multi-body finite element-boundary element model formulated in the time domain to predict vibrations caused by trains passing over the bridge. The vehicle was modelled as a multi-body system, the track and the bridge were modelled using finite elements and the soil was considered as a half-space by the boundary element method. The dynamic response of bridges to vehicle passage is usually studied using moving force and moving mass models. However, the multi-body system allows to consider the quasi-static and dynamic excitation mechanisms. Soil-structure interaction was taken into account by coupling finite elements and boundary elements. The paper presents the results obtained for a simply-supported short span bridge in a resonant regime under different soil stiffness conditions.
