Resumo(s)
Excessive vibrations in the work environment not only harm exposed workers but can also affect the integrity of building structures. This problem was detected in a wine cellar in Alijo ́, Portugal, where a concrete slab is driven to resonance by two vibrating hoppers. In order to address the problem, a strategy combining physical modelling techniques and in-situ vibratory measurements have been developed. The general objective was first to reproduce the qualitative trends observed and then to assess the effectiveness of the proposed solution. The strategy developed here allowed to study how to decrease the vibration amplitude without making structural modifications on the slab, nor serious changes to the vibrating equipment.
