Many experimental researches have carried out predictions of bearing capacity of spread foundations. On the other hand, although many numerical analysis have been also reported, most of them have resulted in in poor predictions of localized deformation patterns and their developments., except a few studies with softening effects or a double-slip theory. We here employ the double-slip theory as well as a non-coaxial plasticity to simulate numerically developments of deformation localization under spread foundations. We report effects of material parameters on development of localied bands of deformation.
