Abstract
An evaluation method of the response of a pile due to an earthquake for the seismic design of medium-rise buildings is investigated based on the analysis with a three dimensional frame model considering soil-structure interaction. The effect of embedment of a structure on a story shear forces, the seismic coefficient for the foundation and the pile response are examined first. The effect of inertial and kinematic interactions on the pile stresses is then evaluated by the so-called seismic deformation method that is frequently used to estimate the response of piles in the practical design. Finally, the effective method for superposing pile response due to inertial and kinematic interaction are discussed.
