Uplift mechanics of unanchored liquid storage tanks self-anchored storage tanksStill, a major dilemma faced by designers lies in the support conditions of the tank, which can either be mechanically anchored via equally-spaced anchor bolts around the perimeter of the tank, or self-anchored (i.e. unanchored) where stability against overturning is offered by the self-weight only. Uplift Mechanics of Unanchored Liquid Storage Tanks self-anchored storage tanksstorage tanks [79] offer an approach that aims to determine the required wall thickness by self-anchored storage tanks via equally-spaced anchor bolts around the perimeter of the tank , or self-anchored (i.e.
