Abstract of the special session:
Increasing densification of cities offers economic and social benefits. Moreover, it contributes to a reduction of greenhouse gas emission by allowing more energy efficient buildings and mass transit systems. On the downside, noise and vibration may cause annoyance, possibly endangering the health and well-being of citizens in densely populated areas. External sources such as rail and road traffic, but also sources inside buildings, are responsible for ground and structure borne vibration that can be felt as whole-body vibration or heard as reradiated noise. The extension of roads and railways as well as the construction of new and modification of existing buildings adds to the complexity and magnitude of the problem. To meet the requirements of sustainable cities, there is a demand for new design methods that provide reliable estimates of the vibration levels, allowing timely decision making.
Hence, this session focusses on the quantification and modelling of the uncertainties related to sources and transmission paths as well as the perception of individuals. Proposed topics for contributions include, but are not restricted to: uncertainty quantification for vibration and noise sources in the built environment; propagation of uncertainties related to dynamic soil–structure interaction and vibro-acoustics; reliability-based vibration mitigation; uncertainties related to the reception of noise and vibration; surrogate models for reliability-based assessment of environmental vibration and noise.
