Numerical modeling of circular footings subjected to monotonic inclined loading on uncemented and cemented calcareous sands

Abstract

The behavior of a rigid circular footing when subjected to inclined loading on cemented and uncemented calcareous sand is investigated. Results from inclined loading tests of a 25 mm diameter foundation are used to assess the applicability of an existing work-hardening plasticity model that describes combined vertical, moment, and horizontal loading behavior. The model makes use of the force resultants and the corresponding displacements of the footing, and allows predictions of response to be made for any load or displacement combination. The results of retrospective modeling of the experiments using this system "macroelement" method are described and compared to the experimental results an..
