Web15 dec. 1992 · ABSTRACT A three-dimensional (3D) analysis of bearing capacity of square and rectangular footings is presented by means of a slice method, assuming that sliding surfaces are composed of a set of log-spirals with different initial radii in the direction of the longer axis of the footing base. Discussions are first made on some fundamental aspects …
