This paper utilizes finite element analysis to study stresses under ring footings resting on two-layered soils. The upper layer differs from the underneath layer in values of the deformation modules. The objective of this research is analysis of the effects of two factors: stiffness ratio and the upper layer depth. The ring footing is numerically modelled as strip load. It is found that the stresses decrease as the value of stiffness ratio increases. But the stiffness ratio effect decreases as the upper layer depth increases. Also, there is a limit value of stiffness ratio for each the upper layer depth. When this ratio exceeds a limit value the effect of stiffness ratio to stresses is insignificant.
