Seismic Response of Large Pile Moored Floating Structures

Presented by Erik Soderberg at the Ports 2019 Conference in Pittsburgh

Pile moored floats are usually not analyzed for seismic motions, since they are often thought to be mostly isolated from ground motions due to the flexibility of the piles and the resistance of the surrounding water. To confirm this assumption for several projects, the authors performed simplified time history analyses on multiple floats to study the effects of water resistance, soil damping, and the gap between the pile and float.
