BEARING CAPACITY FORMULA OF SHALLOW FOUNDATIONS CONSIDERING EFFECTS OF LOAD INCLINATIONS AND SUBSOIL STRATUM

Abstract

This paper proposes a formula widely applicable for calculating bearing capacity of shallow foundations, which can evaluate inclined load action from superstructure and inclined bearing stratum at the same time. The formula is derived using seismic coefficient method and admissible velocity field method. In practice, most bearing capacity formulas assume only influence of load inclination. Then, it was found from the newly proposed formula that in case of strong earthquake level, most of the present formulas might have risk to over-evaluate bearing capacity.
