| Research Abstract |
In general, external forces are not constant values both in time and in space. Shakedown analysis is formulated and applied to the problems of bearing capacity of shallow foundations under variable loads. In the conjunction of the shakedown analysis, mechanical interpretation of shear strength reduction method and improvement of special discretization of a stress field are also discussed. These results will contribute to the advanced and sophisticated evaluation of foundation structures
