Seismic Vulnerability Assessment of Liquid Storage Tanks

Liquid-filled tanks are effective storage infrastructure for water,oil,and liquefied natural gas (LNG).Many such large-scale tanks are located in regions with high seismicity.Therefore,very frequently base isolation technology has to be adopted to reduce the dynamic distress of storage tanks,preventing the structure from typical modes of failure,such as elephant-foot buckling,diamond Seismic Response of Unanchored Liquid Storage Tanks Jan 17,2014 unanchored liquid storage tanks fusion#0183;Unanchored liquid storage tanks under strong seismic loading may exhibit uplifting of their bottom plate,with significant effects on the dynamic behavior and the structural integrity of the tank.In the present paper,base uplifting mechanics is examined numerically through a two-step methodology (a) a detailed finite element shell model of Seismic Fragility Analysis of Steel Liquid Storage Tanks Liquid-containing storage tanks are important structures in industrial complexes.Because earthquake damages to liquid storage tanks can cause structural collapse,fires,and hazardous material leaks,there have been continuous efforts to mitigate earthquake damages using seismic fragility analysis.In this regard,this study focuses on the seismic responses and fragility of liquid storage tanks.
