SEISMIC CALCULATIONS

TANK CALCULATIONS IBC2021/CBC2022

• Calculations in the attached PDF files are stamped by a California Structural Engineer. If a stamp is needed for another state please contact Snyder Industries for availability.
• If an original “wet stamp” calculation is required it must be ordered from Snyder Industries. See Snyder price list for pricing.
• Calculations in the attached PDF files are stamped using the design system coefficients for zip codes in Santa Ana, CA as indicated in the calcs. If calculations are needed using a different zip code and design system coefficients then “site specific” calculations will need to be ordered from Snyder Industries. See Snyder price list for pricing.
• Seismic Systems only available for tanks and sizes listed and only for tanks with molded-in tie down lugs. Contact Snyder for seismic system and calculation availability for tanks without molded-in tie down lugs.
