CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishIn the field of civil engineering, multi-hazard experiments are largely used to study the structure interaction under different extreme environmental conditions. This paper discusses the laboratory experiment needs to investigate the double interaction between earthquake-structure and wind-structure for a high-rise building used as case of study. In particular, the dynamics parameters of an in-scale model was identified though measurements on shaking table. The same model will be used for experiments in wind tunnel. Results have shown that the very small scale of models needed for wind tunnel experiments affects the structural identification in particular for the damping ratio estimation. The uncertainty propagation on the pseudoacceleration spectrum due to the damping ratio variability was discussed.

In particular, the dynamics parameters of an in-scale model was identified though measurements on shaking table. The same model will be used for experiments in wind tunnel.
