Abstract

Past earthquakes confirmed that seismically induced kinematic loads from soil lateral spreading and inertial loads from structure can cause severe damages to pile foundations. The research questions are:

  • How to combine inertial and kinematic loads in design of pile foundations in liquefied soil?
  • How the combination of inertia and kinematics changes with depth?
  • How this combination is affected by long-duration earthquakes?
  • How this combination affects inelastic demands in piles?
