“…Enfin, pour aller au-delà, il serait également néces saire d'étudier la transmission des vibrations aux bâti ments, la gêne occasionnée par les vibrations proprement dites ou par le bruit potentiellement émis dans les bâtiments (notion de « bruit solidien » (Coquel, 2008 ;Fiala et al, 2007)). L'évolution de la réglementa tion devrait tenir compte de l'ensemble des différents aspects.…”

Railway vibrations induced into the soil: experiments, modelling and isolation AbstractRailway traffic induces cyclic and dynamic loadings in the track structure but also in the close environment (Degrande et al., 2006;François et al., 2007;Kausel, 2008;Lefeuve-Mesgouez et al., 2002;Paolucci et Spinelli, 2006). The analysis of such excitations and their effects (e.g. vibrations, waves, etc.) is fundamental to estimate their level and mitigate their potential consequences (settlements, nuisances, etc.). After a brief summary of the current regulations, in situ experiments show the variability of the parameters characterizing the main phenomena (wave propagation into the soil, induced vibrations, etc.). The main dynamic laboratory experiments are then discussed. They allow the estimation of the dynamic features of the materials (e.g. resonant column test), but also a simplified analysis of the main phenomena under controlled conditions (e.g. experiments in a geotechnical pit, centrifuge tests). The vibratory sources and the impedance ratios between the various soil layers (or some inclusions) being known, it is then possible to model some specific or actual configurations through theoretical (transfer functions) or numerical (e.g. finite elements, boundary elements) methods. Parametric studies allow the analysis of the propagation phenomena and the attenuation process in the soil in order to investigate the spatial variations of the vibrations amplitude in such various configurations. Finally, it may be useful to consider mitigation or isolation techniques in order to limit the consequences of the induced vibrations (e.g. vibratory nuisances, radiated noise). Several experimental and numerical results illustrate this key issue.

“…Similarly, François et al [9] presented an analysis of the SSI influence in the road traffic induced vibrations on buildings, and they concluded that the vibration levels depend on the relative stiffness between the foundation and the soil. Fiala et al [10] analysed the effectiveness of different mitigation system in buildings, using a numerical model developed in two dimensions and a half (2.5D) and based in the substructure method. Mitigation system consisted in the complete or partial isolation room, and also in the use of dampers at the building foundation.…”

“…FE models have been used for analysis of wooden structures by, among others, Brunskog and Davidsson [5], Løvholt et al [6], Maluski and Gibbs [7], and Fiala et al [8]. For large building structures, a solid FE model will contain millions of degrees of freedom if individual joist and studs are to be modelled in detail.…”

Abstract. Noise is a nuisance to people, and buildings should therefore be designed to prevent propagation of sound and vibration in the audible frequency range as well as the range of frequencies relevant to whole-body vibrations of humans. In heavy structures made of concrete and masonry, a source with high energy content is required to mobilise the inertia. However, for lightweight building structures made of wood, less energy is required to produce vibrations since the mass is smaller. This leads to a high risk of sound and vibration propagation in terms of direct as well as flanking transmission.However, lightweight structures are typically periodic in the sense that joists and studs are placed with a repetition of the same distance along each panel. Further, in a multi-storey building the geometry of entire rooms may be repeated along the horizontal and vertical directions. Such periodicity is known to result in pass bands and stop bands regarding wave propagation. The paper focuses on analysing and quantifying the effects that a change in the structure, especially regarding the periodicity, has on the overall dynamic performance in the low to mid frequency range up to 250 Hz.The analysis is performed by means of a finite-element model. Firstly, a rigorous solid finite-element model is made for each wall and floor panel. Secondly, reduced models with significantly fewer degrees of freedom are obtained by component mode synthesis, augmenting Guyan reduction with a number of internal Eigen modes. Using a substructure approach, the panels are then combined to a global model of a multi-storey building. Example Eigen modes of a single floor panel and the global building are presented. Vibration caused by point force excitation is finally analysed in the frequency domain as well as the time domain.
