Resumo(s)
Bearing capacity of shallow foundations is commonly determined using formulations initially considering centered vertical loading on a strip horizontal footing and then corrected for taking into account deviations from this idealsituation, such as eccentricity and inclination of the loads and of the shape of the foundation. Most bearing capacity formulations don't include correction factors considering seismic actions. In this work, pseudostatic limit analysis calculations simulating the seismic action with horizontal and vertical seismic coefficients, were performed with mechpy, a program developed within the authors' team which implements a finite element formulation of the limit analysis theorems. Based on the results of both lower and upper bound calculations, seismic and load inclination bearing capacity factors are proposed.
