000019657 520__ $$2eng$$aLiquid storage tanks are vital lifeline structures and have been widely used in industries and nuclear power plants. In performance-based earthquake engineering, the assessment of probabilistic seismic risk of structural components at a site is significantly affected by the choice of ground motion intensity measures (IMs). However, at present there is no specific widely accepted procedure to evaluate the efficiency or sufficiency of IMs used in assessing the seismic performance of steel storage tanks. The study presented herein concerns the probabilistic seismic analysis of above-ground steel storage tanks subjected to several sets of ground motion records. The engineering demand parameter for the analysis is the compressive meridional stress in the tank wall, which could lead to an elephant's foot buckling failure mode at the bottom shell course of the wall. The efficiency and sufficiency of each alternative IM are quantified by results of time history analyses for the structural response and a proper regression analysis. According to the comparative study results, this paper proposes the optimal IMs with respect to the above demand parameter for a portfolio of steel storage tanks.
