The finite element method (FEM) is commonly used to verify seismic performance in the design of various facilities, such as buildings with pile foundations and sheet pile quay walls in Japan. It is very important to conduct validation and verification of numerical analysis. Although validations of numerical analysis is usually conducted, it is very difficult to conduct verification of non-linear problem. We did verification of modeling of pile end resistance by using FLIP ROSE. We conducted the simulation of monotonic loading test and cyclic loading test of a pile. The pile penetration was represented as the enforced displacement and the enforced load at the pile head nodes. The load-settlement relationship of enforced displacement did not agree with that of enforced load when the effective confining pressure of ground elements at the pile tip goes zero. However, when the ground nodal points within the pile diameter are constrained not to occur tensile stress, the load-settlement relationship of enforced displacement agreed well with that of enforced load. Finally, we could confirm the verification of modeling of pile end resistance using FLIP ROSE.
