May 11,2006 mechanically anchored tanks roof plates#0183;Bear in mind that if this is a self-supported cone roof you can contribute the entire weight of the roof plate to the overturning resistance (as opposed to a structural roof).The sliding question comes-up all the time and while not proposterous,it is still over conservative to consider this as the only reason to anchor a tank.frangible roof tank as per api 650 - API (American The intent of frangible roof design is for the roof-to-shell joint to fail preferentially to the shell-to-bottom.This you may have already known.However,in order to achieve this,it is necessary to limit the roof-to-shell strength.So,item 5 was added to accomplish this.You are correct that these items are based on an self anchored tank.design problems of anchoring of aboveground steel tanks Tank's shell 2.Plate 3.Tanks bottom 4.Superior plate 5.Anchor bolt 6.Vertical ribs 7.Inferior plate 8.Stiffening ring In some cases anchor bolts bear tension and shearing forces and this case imposes the relevant details of their chairs (Fig.2) Fig.2.Anchor bolts for tension and shearing forces,and their chair 1.Tank shell 2 Plate 3.
