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 this paper the aeroelastic behaviour of tall buildings or towers is studied based on an equivalent one-dimensional beam model immersed in a three-dimensional space. The beam is internally constrained, so that it is capable to experience shear strains and torsion only. The model accounts for the torsional effect induced by the rotation of the floors around the tower axis; the macroscopic shear strain is produced by bending of the columns, accompanied by negligible rotation of the floors. Aerodynamic forces are evaluated through the quasi-steady theory, referring to a section model under stationary wind. The effect of mechanical and aerodynamic coupling on the critical galloping conditions is analyzed.
