models that are suitable for estimating the internal forces and moments,both for anchored and unanchored liquid storage tanks (e.g.[27,28]).Furthermore,the periods of vibration of the two components (i.e.impulsive and convective) are well-separated for practically any tank,thus allowing the decoupling of their respective responses.Seismic Performance Evaluation of Liquid Storage Tanks A simplified approach is presented for the seismic performance assessment of liquid storage tanks.The proposed methodology relies on a nonlinear static analysis,in conjunction with suitable strength ratio-ductility-period relationships,to derive the associated structural demand forSeismic Intensity Measures for Above-Ground Liquidthe seismic risk assessment of liquid storage tanks.Using a surrogate modelling approach on a squat tank that is examined both under anchored and unanchored support conditions,incremental dynamic analysis is adopted to generate the distributions of response parameters conditioned on each of the candidate intensity measures.
Three cylindrical liquid storage tanks of different aspect ratios are modeled and examined both as anchored and unanchored.The results are aimed at possible revisions in the relevant seismic SURROGATE MODELLING AND SENSITIVITY ANALYSIS OFAbstract.Large-capacity atmospheric tanks are widely used to store liquids,such as oil or liquefied natural gas.The seismic risk of such industrial facilities is considerably higher compared to ordinary structures,since even some minor damage induced by a ground motion may have uncontrollable consequences,not only on the tank but also on the environment.SIMPLIFIED MODEL FOR THE SEISMIC PERFORMANCEresponse of anchored and unanchored liquid storage tanks have been presented by Fischer ,Rammerstorfer et al.,Fischer et al.,with particular emphasis on design
