Abstract
This paper presents an analytical solution to determine the kinematic and inertial response of a vertical pile embedded in a soil layer and subjected to vertical seismic excitation due to earthquake loading. The pile is assumed to have a circular cross section and perfectly connected to the soil. Also the soil stratum is assumed to be homogenous. The approach of Novak and his associates is used to derive the governing differential equation of the pile subjected to vertical harmonic vibrations. The kinematic response of the pile is first obtained considering stress free condition at the pile head and the ground surface. The inertial response of the pile is also determined when a concentrated mass exists at the pile head. It will be shown that existence of the concentrated mass at the pile head has no significant effect on the pile response. In fact, the general finding indicates that the inertial response of the pile is negligible compared with the kinematic pile response.
