The detachment of the bottom e.g.sliding and overturning of the tank shall be avoided by 16 anchors positioned at equal distance around the shell,thread M39,made from steel S355.All these anchor bolts have pin joints with the upper plate and are fixed to the foundation.Anchors shall not bear pressures forces.The tapered beam model for bottom plate uplift analysis of In the case of an anchored tank,the tank bottom edge is fixed to the foundation.If the tank is unanchored,partial lifting of the tank's bottom may occur,and a strongly nonlinear problem has to Tanks Silos - Flexible Lifeline SystemsUser-friendly and uncompromising fall protection for tanks.Flexible Lifeline Systems (FLS) is prepared and ready to handle your tank safety needs.Our Railings,Anchors,Lifelines, Safe Access Systems are designed to be user-friendly and non-intrusive while providing continuous,complete,and uncompromising fall protection while working at height.
