You are correct that these items are based on an self anchored tank.However,the addition of anchorage does not significantly affect the shell-to-bottom joint strength with regards to rupture of the corner weld. For a standard (carbon steel) tank,an annular plate is required if mandated by 5.5.1,or by Appendix M for a heated tank,or may design problems of anchoring of aboveground steel tanks Tank shell 2 Plate 3.Tanks bottom 4.Superior plate 5.Anchor bolt 6.Vertical ribs 7.Inferior plate 8.Stiffening ring 2.Research of the influence of anchors chairs The influence of the anchors chairs shall be researched for the tank T003,in La Reunion.The tank have the following parameters (Table 1) Table 1.Tank design - wordFeb 04,2016 self anchored flatbottom tanks deck plates#0183;J = [ ( ) ] Anchorage Ratio Criteria No calculated uplifted The tank is self- anchored.1.54 Tank is uplifting,Check shell compression requirements.Tank is self-anchored.Tank is not stable Table 4-6 Anchorage Ratio Criteria = Weight of tank shell portion of roof supported by shell = + (Roof load acting on shell) 32.

Tank Anchorage,Overstrength Factor,and Overturning

If you are in SDC A or B,the detailing requirement doesn't apply.So in those cases you can just design the anchors for the loads,or in some situations you can design the tank to be self-anchored.Section 15.7.5 kicks you to the applicable reference document to determine whether or not your specific tank or vessel qualifies to be self-anchored.Tank Anchorage,Overstrength Factor,and Overturning If you are in SDC A or B,the detailing requirement doesn't apply.So in those cases you can just design the anchors for the loads,or in some situations you can design the tank to be self-anchored.Section 15.7.5 kicks you to the applicable reference document to determine whether or not your specific tank or vessel qualifies to be self-anchored.Steel Water Storage Tanksstruction phases of steel tanks and seismic retrots.Meier has led many standards-making committees,including American Water Works Asso-ciations Steel Tank Committee,Committee on Welded Steel Tanks,and the D170 Composite Elevated Water Tank Committee.He has also served on the Steel Tank Institute/Steel Plate Fabricators Association
