Abstract : The emergence in the last 5 years of Tall Wood Buildings is part of the development of the wood industry and represents one of the relevant responses to current environmental and urban densification constraints. Among the technical challenges posed by such buildings, horizontal oscillations are a key issue. Indeed, the strength / lightness ratio of wood gives buildings interesting properties regarding earthquake but also more difficult to manage regarding wind loads, with induced vibrations that can be detrimental to the comfort of the occupants. Opertional Modal analysis on wooden structures showed significant variations in the dynamic properties of wooden high-rise buildings (frequencies, damping…) ans many questions are related to the evolution over time (at during its use) of the dynamic properties of wood high-rise buildings. The scientific objectives of this experiment are therefore: the modal analysis of the wooden structure under ambient vibrations; the evaluation of modal fluctuations over time and their impact in terms of building performance (comfort and earthquake); the interpretation of the physical processes at the origin of these fluctuations. The selected building is a wooden high-rise (9 stories) building under construction (2020-2021) as part of the "Le Haut-Bois" project .
