Magic R Seismic Design of Water Tanks

The inferred R (in the 1978 code) varies whether or not the tank is anchored or unanchored.This is a direct result of the 2.5 (unanchored) and 2.0 (anchored) multipliers that the 1978 code authors used,which was geared to penalize unanchored tanks (i.e.,require a higher base shear force for design).Once we convert the 1978 base shearMETHOD STATEMENT FOR STORAGE TANKS - 123docAug 25,2016 unanchored tanks erection requirements#0183;STORAGE TANKS WITH ROOF Rev-0 Page 18 1500 MTPD Phosphoric Acid plant 4500 MTPD Sulphuric Acid plant METHOD STATEMENT 4th shell 1st plate erection,alignment on bottom plate METHOD STATEMENT FOR STORAGE TANKS WITH ROOF Rev-0 Page 19 1500 MTPD Phosphoric Acid plant 4500 MTPD Sulphuric Acid plant METHOD STATEMENT 4th shell 2nd plate fitFall Protection for Aboveground Storage Tanks - Flexible If the top of a tank is not a platform under the analysis called for in OSHAs guidance document,the guardrail requirements of that standard would not apply.However,if perimeter guarding is not provided,fall protection in the form of personal protective equipment would likely be required by unanchored tanks erection requirements#167;1910.132(a).
