Those tanks that are continuously supported with a flat bottom are typically larger storage and fermentation tanks,and are called flat bottom tanks.The flat bottom tanks are also anchored to concrete slabs.Damage to these tanks observed after the 2010 Maule Earthquake included anchorage failure and buckling of the stainless steel tank wall.Post-Installed Anchorage Solutions for Holdowns and Bases Allowable Stress Design (ASD) values are obtained by dividing Load Resistance Factor Design (LRFD) capacities by 1.4 for seismic and 1.6 for wind.Load values based on the following minimum concrete strength of 2,500 psi,dry hole temperature range 1 and continuous special inspection.Reference ICC-ES ESR-2508 for further information.
