Seismic Safety of Large Vertical Steel Cylindrical TanksGrounds

The objectives of this paper are to highlight the principal effects of base uplifting on the seismic response of ground supported cylindrical steel tanks that are unanchored at their Base. Specific areas targeted for improvements are related to: a) Estimation of the loads exerted on anchored tanks, particularly the overturning moment, b) Estimation of the compressive stress and allowable shell buckling stress at the shell bottom.
