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?

Development of a Design Guideline for Pile Foundations Subjected to Liquefaction-Induced Lateral Spreading

Portland State University

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?
