Evaluation of the Dynamic Bearing Capacity of a Masonry Building by Means of a Characteristics Line Method

Strengthening works performed only in the superstructure are often insufficient in preventing damage in buildings during seismic events. They can avoid the complete collapse of the structure but they cannot ensure the total safety and serviceability of the whole building, often significantly damaged because of its foundation movements. The goal of this paper is to analyze the dynamic behavior of the shallow foundation of a full-scale masonry building in terms of bearing capacity, on the basis of the dynamic characterization of the subsoil and of the local site response. As suggested by Eurocode 8 (EC8), the design vertical resistance was evaluated taking into account the possible effects of the soil inertia forces by means of a new numerical model, developed at the University of Catania, based on the characteristics line method of the theory of the limiting equilibrium. The seismic bearing capacity analysis was also performed according to the limit analysis method proposed by Richard et al., and to the kinemataic approach of the yield design theory mechanism proposed by Paolucci & Pecker. The results were compared with those provided by the worldwide used Brinch-Hansen method, which ignore the presence of inertial forces in the soil.
