ABSTRACT
In seismic analysis, both the earthquake loads due to direct ground motion transmission to the structural supports and the so-called “seaquake” loading, due to the water transmission of compressive waves originated at the seabed, are worth of special attention. Especially for seaquake, no or scarce research work on SFTs has been developed until now. As an additional external loading, it works like a hydrodynamic pressure due to compression waves (water cannot transmit shear waves) traveling through the water, generated by the earthquake motion at the seabed, which needs special investigations for the potential damaging effects that such waves may cause on offshore structures and floating systems.
