Additional information
Paper presents new interpretation of kinematic pile bending at interface separating two soil layers of different stiffness. Kinematic pile bending is expressed as superposition of two counteracting mechanisms: (1) free-field bending and (2) perturbative interface bending, depending mainly on interface depth, pile-soil stiffness contrast and layer-stiffness contrast. On basis of this mechanism it is demonstrated that depending on value of governing parameters, both zero interface bending and equal bending between pile head and interface are possible. These previously unsuspected phenomena may have profound effect on design of piles against seismic loads.
