The dynamics of a medieval tower, inside the Basilica of San Benedetto in Ferrara (Italy), subjected to transversal dynamic loadings has been analyzed by using a distinct element code which implements the Non-Smooth Contact dynamics method. Since the contact between blocks is governed by the Signorini’s impenetrability condition and the dry-friction Coulomb’s law, the tower exhibits discontinuous dynamics. The sliding motions of blocks are non-smooth functions of time. Numerical simulations are performed with the aim of investigating the influence of the friction coefficient but also of the amplitude and frequency of the excitation at the base.

Abstract
The dynamics of a medieval tower, inside the Basilica of San Benedetto in Ferrara (Italy), subjected to transversal dynamic loadings has been analyzed by using a distinct element code which implements the Non-Smooth Contact dynamics method. Since the contact between blocks is governed by the Signorini’s impenetrability condition and the dry-friction Coulomb’s law, the tower exhibits discontinuous dynamics. The sliding motions of blocks are non-smooth functions of time. Numerical simulations are performed with the aim of investigating the influence of the friction coefficient but also of the amplitude and frequency of the excitation at the base.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
