Figure 1 shows a sliding wedge on an elastic foundation under the gravity load. The bottom side of the foundation is constrained in all directions. The left side of the wedge is connected to 9 linear 2-node springs in the horizontal direction. Horizontal distances are determined for the four cases of frictional constants and spring stiffness as summarized in Table 1. Geometric nonlinear analyses are carried out to obtain the horizontal displacements, which are then compared with the reference values.
