design problems of anchoring of aboveground steel tanks

To eliminate the threat from free moving,the steel facilities are often anchored to the foundation.This solution is not recommendable,and in standards [1] and [2] it is positioned on the last place.Despite the standards recommendations when the conditions of exploitation are strait and/or extreme,the steel vertical tanks must be anchored.design problems of anchoring of aboveground steel tanks 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.Vertical,Underground Plastic Water Tanks Plastic-MartVertical water tanks - These above ground water tanks are ideal for a variety of uses that include storing potable drinking water,harvesting and collecting rainwater and as an emergency water supply..Metal tanks are made of steel.The steel has galvanized coating that provides quality water storage for 20 years plus.Light will not break down or discolor the tank shell and will not crack in
