To develop damage state–dependent seismic fragility
functions for pile wharves supported on liquefiable soil.
Seaports in seismically active regions may often undergo
strong aftershocks following a mainshock event. Due to the
short time interval between events in such a seismic
sequence, retrofit interventions are often impossible; as a
result, the aftershock acts in already damaged structures.
Pile–supported wharves are particularly vulnerable to such
seismic sequences with the main cause of damage being the
liquefaction of soft underlying soils and/or hydraulic backfills
