Highlights

  • During earthquakes, pile foundations will be subjected to lateral ground vibrations, referred to as kinematic loads, along with the vibrations induced by superstructure, called inertial loads

  • A series of dynamic centrifuge experiments was performed at 60g on a model single pile and two 3×1 row pile groups with different pile spacing in a two-layered soil model to investigate the influence of pile spacing on the dynamic behaviour of pile groups

  • The pile group accelerations were relatively smaller in widely spaced pile group compared to a closely spaced pile group when both the pile groups respond at a similar normalised frequency (f/fsps) ratio
