design problems of anchoring of aboveground steel tanks

The loads which impact on them are self-weight,snow,wind,earthquake,overpressure and vacuum.When the earthquake,overpressure and wind loads have high values,it is possible that the tank overturn or going to slide.To eliminate the threat from free moving,the steel facilities are often anchoreddesign problems of anchoring of aboveground steel tanks It is assured that the bottom shall bear only pressures forces.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.[DOC]APPENDIX QLOW-PRESSURE STORAGE TANKS FOR self anchored flatbottom tanks Pneumatic Pressure#0183;Web viewIn the case of a double-wall tank with an open-top inner tank,where the air pressure acts against the outer tank and the inner tank is thus not stressed by the air pressure,the inner tank may be emptied of water before the pneumatic pressure test begins.Q.6.5.2 The test pressure shall be held for 1 hour.
