In this paper the behavior of single piles under lateral impact is investigated by using the performed pendulum and bogie tests. Three types of soil deposits were used in the experimental tests including hard clay, loose sand and crushed limestone. The acceleration and displacement of the striking mass are measured. The results show that the soil response to impact is a function of soil stiffness; however the inertia and damping resistance are also important contributors. In order to model the system, a Single Degree of Freedom (SDF) model with two different basic materials is used to find the best simple model to predict the behavior of piles under impact. Finally an advanced model with multi degree of freedom is used to analyze a single pile under the pickup truck impact with 60 miles per hour. The results of the simple model and the experimental tests are compared with the LS-DYNA simulations.
