000010546 520__ $$2eng$$aThe present study discusses about the seismic risk assessment of un-anchored steel tanks when a strong earthquake excitation develops a plastic deformation at the base plate due to a rocking motion of the tank. Current seismic design guidelines underestimate the seismic safety of buckling failure at the side wall or shell plate, because the stiffness degradation of the tank is overestimated with the structural characteristic factor Ds. The present study proposes an exact estimation approach of the seismic safety of buckling failure at the shell plate as well as the crack failure of the base plate. The seismic performance of the tank is also developed using a limit state design method to provide the fragility curves for the damage modes of the shell plate and base plates.
