Abstract
Shakedown analysis on a bearing capacity problem of c-φ material subjected to surface moving loads is investigated in this paper. A numerical code based on the hybrid type formulation is developed and applied to boundary value problems to check its performance. Reduction of bearing capacity due to the movement of the loads is quantitatively evaluated. The threshold value of the lateral moving distance which reflects the influenced area of moving loads is also evaluated. The advantages of shakedown analysis in comparison with the evolutional method, such as incremental form elasto-plastic analysis are also discussed.
