of storage tanks have shown that only full (or nearly full) tanks experienced catastrophic failures.Low H/R tanks only suffered cracks in conical roof connection,or damage by oating panel sinking.The most common shell damage is the elephant foot buckling (EFB).For unanchored tanks and H/R 0.8,EFB is not experienced but the base Seismic response of unanchored liquid storage tanksThree 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 design provisions of EN 1998-4 and API 650.Seismic fragility and dynamic behavior of atmospheric The main purpose of the research carried out in the aim of this PhD dissertation has been the analysis of the dynamic behavior of on-grade cylindrical steel storage tanks.This has been done through two main research fields the evaluation of tank seismic fragility and the analytical modeling of the tank dynamics when subjected to the ground acceleration.
