The passage of seismic waves through the soil may cause two important kinematic effects on pile foundations: the motion occurring at the foundation level to be different to the free-field motion (with no structure); significant curvatures to be developed by the piles, which can experience considerable bending moments at great depth, not depending on the oscillation of the superstructure. In this paper, a lumped-mass parameter model is used to analyse the kinematic response of the piles. This formulation incorporates p-y curves described by the hyperbolic model along with extended Masing criteria. To validate the proposed approach, comparisons with other theoretical and experimental results are reported.

Abstract
The passage of seismic waves through the soil may cause two important kinematic effects on pile foundations: the motion occurring at the foundation level to be different to the free-field motion (with no structure); significant curvatures to be developed by the piles, which can experience considerable bending moments at great depth, not depending on the oscillation of the superstructure. In this paper, a lumped-mass parameter model is used to analyse the kinematic response of the piles. This formulation incorporates p-y curves described by the hyperbolic model along with extended Masing criteria. To validate the proposed approach, comparisons with other theoretical and experimental results are reported.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
