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.Storage Tank Detail - DocShare.tipsCryogenic Tank Annular Plate to Annular joint BUTT joint 33.Cryogenic Tank Annular Plate to Annular joint BUTT joint Full RT 34.ATM Tank Annular Plate to Annular joint Backing Strip Used RT only Sport Area 35.ATM Tank Plate ASTM SA-36,SA-537CL-1,SA-537CL-II,SA-516GR-60 IS2062GR-B 36.ATM Tank Plate ASTM SS/SA-240Type304,304L,316,316L 37 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
