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 a model for the dynamic analysis of retaining walls subjected to seismic excitation is described. The dynamic equilibrium equation is integrated in time domain for the analysis of the sliding response of rigid retaining walls. Since the soil-wall system changes its configuration during motion due to the displacement of the soil wedge behind the wall, the variation of the height of soil acting against the wall results in an important factor in the dynamic equilibrium. Furthermore the changes in the system's configuration involve a variation in the soil mass partecipating to the system motion. Such variation is considered in the dynamic equilibrium as well. The response of the system in terms of displacements is computed for different kinds of excitation and a parametric analysis is performed in order to evaluate the influence of ground motion features on the system response.
