Seismic bearing capacity of circular footings: a yield design approach

Jean Salençon, Charisis Theodorou Chatzigogos and Alain Pecker

Vol. 4 (2009), No. 2, 427–440
Abstract

As developed during the past decades, the yield design theory provides an approach to the stability analysis of civil engineering structures under seismic conditions which has been often used, explicitly or implicitly. New results related to circular footings resting on a purely cohesive soil, taking into account the horizontal inertia forces, are presented in this paper for practical applications to the safety coefficient to be applied to the vertical load when designing seismic foundations.
