As shown in FIGS.3B and 3C,a distance between the first retaining member 5 a and the second retaining member 11 is smaller than a distance between a distal end of the anchored portion 24 b and the second side 22 b 2,so that the tank 2 b is capable of rotating relative to the supporting body 6 b substantially around the first retaining member Tank Surface Damage Pitting,Corrosion,and DeformationFor example,when you are vacuuming your tank,the sides may flex in and out as the pressure changes inside of your tank.Deformation from fabrication on a fermenter chimney The best way to get the most life out of your tanks is a regular maintenance and inspection program.Tank Anchorage,Overstrength Factor,and Overturning My question relates to ASCE 7 Chapter 15,particularly 15.7.5.I am designing the anchorage for a saddle supported liquid storage tank.Section 15.7.5 makes it clear that the overstrength factor is NOT to be used for tank anchorage calculations,because they are trying to force a ductile yield in the anchor,requiring the concrete to develop the full steel strength of the anchors in tension.
