ABSTRACT
Pile moored floats, such as floats for ferry terminals, ferry maintenance facilities, and other floating waterfront structures, often rely on long vertical piling to provide lateral support while allowing the floating structures to move up and down with changing water levels. These structures are often considered seismically isolated due to water resistance and are often designed without seismic evaluation. Simplified spreadsheet time history analyses were made to analyze the seismic response of several pile moored floats designed for the San Francisco Bay Area. The analyses show that water resistance does not significantly reduce float response, such that seismic evaluation of these structures is recommended for high seismic regions, particularly if the float is sheltered and storm loading conditions are not severe.
