Seismic Response of Floating Roof Storage Tanks

loads can induce localized plastic deformations in the tank bottom plate,shell walls,and roof.The focus of this paper is the seismic liquid sloshing response of floating roof storage tanks (Figure 1).Seismic loading will induce both impulsive (fluid mass) and convective (liquid sloshing) loads on the tank walls.Seismic Response of Floating Roof Storage Tanksloads can induce localized plastic deformations in the tank bottom plate,shell walls,and roof.The focus of this paper is the seismic liquid sloshing response of floating roof storage tanks (Figure 1).Seismic loading will induce both impulsive (fluid mass) and convective (liquid sloshing) loads on the tank walls.Seismic Compliance Frequently Asked Questions - OSHPD21.Is the fuel storage requirement based on 96 hours or 72 hours? Are the fuel storage requirements based on fuel consumption of the generators at rated capacity or the actual load for the facility?# OSHPD enforces a minimum of 72 hours of fuel storage for the new NPC-5 building and not the 96 hours required by NFPA 101.
