“…Simplified building models have been achieved by considering infinitely long buildings [34,35], infinitely high buildings [36] and infinitely high buildings with flexible floors [37]. Simple finite structures composed of columns and floors have been used, in [38] a single column and infinitely large floors, and in [39] multicolumn and multi-floor bay models.…”

A simple and fast prediction scheme is presented for train-induced ground and building vibrations. Simple models such as (one-dimensional) transfer matrices are used for the vehicle–track–soil interaction and for the building–soil interaction. The wave propagation through layered soils is approximated by a frequency-dependent homogeneous half-space. The prediction is divided into the parts “emission” (excitation by railway traffic), “transmission” (wave propagation through the soil) and “immission” (transfer into a building). The link between the modules is made by the excitation force between emission and transmission, and by the free-field vibration between transmission and immission. All formula for the simple vehicle–track, soil and building models are given in this article. The behaviour of the models is demonstrated by typical examples, including the mitigation of train vibrations by elastic track elements, the low- and high-frequency cut-offs characteristic for layered soils, and the interacting soil, wall and floor resonances of multi-storey buildings. It is shown that the results of the simple prediction models can well represent the behaviour of the more time-consuming detailed models, the finite-element boundary-element models of the track, the wavenumber integrals for the soil and the three-dimensional finite-element models of the building. In addition, measurement examples are given for each part of the prediction, confirming that the methods provide reasonable results. As the prediction models are fast in calculation, many predictions can be done, for example to assess the environmental effect along a new railway line. The simple models have the additional advantage that the user needs to know only a minimum of parameters. So, the prediction is fast and user-friendly, but also theoretically and experimentally well-founded.

“…Buildings have been often calculated without the underlying soil or with a very stiff soil [33,[38][39][40][41][42]. The soft soil, however, yields an amplitude reduction with increasing frequency, modifies the resonance frequencies and mode shapes and provides a strong radiation damping.…”

“…By improving the 1D impedance model, Zou et al [ 26 ] proposed a 2D impedance model for floor slab vibrations. Clot et al [ 27 ] assumed that vertical ground‐borne vibrations are transmitted to floors through building columns, and then they presented a three‐dimensional (3D) building‐soil analytical model for the floor slab vibrations. Lopes et al [ 28 ] substituted floor slabs with lumped mass and beam elements, and then established a 3D building‐soil numerical prediction model to predict railway‐induced building vibrations.…”

This paper presents a new three-directional isolator and a new prediction model for base isolation method of buildings to improve the comfort of occupants under subway-induced environmental vibration. The mechanical properties of the isolator were tested in a laboratory. The results indicated that the stiffness values can satisfy the isolation requirements for environmental vibrations by increasing the thickness of rubber layers, and the sliding bottom is beneficial for protecting the new isolator from instability failures under earthquakes. The suppression effectiveness of the new isolator for three-directional subway-induced environmental vibrations was then investigated via field experiments with a full-scale building. Further, the tri-axial comfort of occupants inside the building is enhanced significantly. Finally, using the measured data from the field experiments as an input, the new prediction model was proven to be effective for evaluating the vertical vibration levels of the base-isolated building. As the new prediction model only includes a few of the most influential floor slabs, the modeling workload and computational cost of the prediction analysis are eased. Therefore, the new isolator and the prediction model are beneficial for improving the service performances of the base isolation method, especially for the buildings near subway transportation and in seismic areas.

“…However, the influence of these interaction effects is not a well-studied area for traffic-induced building vibrations. Exceptions include the study of the effect of structural modifications to the receiving building and its surroundings in order to mitigate the vibrational response induced by ground sources [3,4,5,6,7,8].…”

Urban densification, despite the economic and social opportunities it offers, brings with it challenges to the well-being of citizens. A direct effect of densification is the rise in noiseand vibration-producing sources, which can lead to both health and comfort issues. In determining the risk associated with excessive vibration levels, the distance between the source and the receiver or target building, the ground properties, and the building type, are all important factors. In this paper, we are concerned with the effect that adjacent buildings have on the prediction of the vibration levels in a residential building, caused by external ground surface loads. The parametric studies were conducted using a coupled finite element model of the ground and the buildings. The analyses were conducted in the frequency domain, and vibrational velocity levels were computed at the receiver building in order to assess how building adjacency affects the receiving building's vibrational response. 5610 COMPDYN 2019 7 th ECCOMAS Thematic Conference on Computational Methods in Structural Dynamics and Earthquake Engineering M.
