About this file
This document provides specifications for concrete foundations for aboveground storage tanks. It includes design requirements for cylindrical and rectangular tanks across different seismic zones. Foundation dimensions, reinforcing steel requirements, and anchor bolt specifications are provided for a range of tank volumes and configurations according to established design standards. Notes cover design assumptions, reference codes, load considerations, and other parameters to ensure foundations are appropriately engineered for each project scenario.
The related federal contract opportunity is for removal and installation of a storage tank at the DeSoto National Wildlife Refuge. The solicitation seeks qualified firms to carry out this infrastructure project in accordance with the detailed foundation specifications and established engineering practices for aboveground tank installation. Adherence to all noted design criteria will ensure structural integrity for the replacement tank under relevant environmental and seismic conditions.

FOUNDATION NOTES FOR CYLINDRICAL TANKS
Jimmy Dale Schroeder, P.E.
Date: 12/6/01 Revised: 1/8/00
1) All designs are based upon the 1997 Uniform Building Code requirements.
2) Tank sizes are as specified by the Steel Tank Institute.
3) All slab foundation dimensions are "minimum" requirements.
4) Only loads imposed by the tank and its contents have been considered.
Additional loads such as, but not limited to, traffic loads or piping loads have not been considered. These foundations may not be adequate for these conditions and concrete thickness, rebar type and spacing will require additional design.
5) Local codes may affect the slab foundation requirements.
6) Design conditions assumed are as stated in the calculations. Actual conditions that are different than these assumptions must be evaluated separately. Conditions assumed in these designs include:
Wind Speed Wind Exposure Seismic Zone Seismic Near-Source Factor Occupancy Category Concrete Strength Rebar Yield Strength Allowable Soil Bearing
7) Anchor Bolt diameters are the minimum required exclusive of corrosion allowance.
Larger bolt diameters may be required to allow for any required corrosion allowance.
8) Minimum bolt grade of material is A307.
9) Embedded length of bolt is the minimum length of the bolt that is embedded in the concrete.
Additional length is required for the projection above the concrete to attach the tank support.
10) The design is based upon a specific saddle configuration. Any changes in the saddle design or configuration requires a review of the foundation design.

FOUNDATION NOTES FOR RECTANGULAR TANKS
Steel Tank Institute Date: Revised: 12/15/99
1) All designs are based upon the 1997 Uniform Building Code requirements.
2) Tank sizes are as specified by the Steel Tank Institute.
3) All slab foundation dimensions are "minimum" requirements.
4) Only loads imposed by the tank and its contents have been considered.
Additional loads such as, but not limited to, traffic loads or piping loads have not been considered. These foundations may not be adequate for these conditions and concrete thickness, rebar type and spacing will require additional design.
5) Local codes may affect the slab foundation requirements.
6) Design conditions assumed are as stated in the calculations. Actual conditions that are different than these assumptions must be evaluated separately. Conditions assumed in these designs include:
Wind Speed Wind Exposure Seismic Zone Occupancy Category Concrete Strength Rebar Yield Strength Allowable Soil Bearing
7) Anchor Bolt diameters are the minimum required exclusive of corrosion allowance.
Larger bolt diameters may be required to allow for any required corrosion allowance.
8) Minimum bolt grade of material is A307.
9) Embedded length of bolt is the minimum length of the bolt that is embedded in the concrete.
Additional length is required for the projection above the concrete to attach the tank support.
10) The design is based on supports being equally spaced.
11) The minimum support size as specified by STI is C6x8.2.
12) The minimum support size as specified by the Steel Tank Institute is adequate for the loads imposed on most of the tanks.
13) For tank sizes marked "*", the supports must be modified by attaching a minimum 1/4" thick plate to the channel to create a rectangular box section rather than an open channel section. This plate must be seal welded all around to the channel section. As an alternative a larger channel section equal to at least a C8x11.5 may be used.
14) For seismic zone 4, the Near-Source Factor (Na) as defined by UBC Table 16-S is taken as 1.0.
If a higher Near-Source Factor is required based upon the nearness of the tank to a seismic fault, the tank, supports, anchorage, and foundation shall be evalulated by a qualified Registered Professional Engineer.
15) The Occupancy Category as defined by UBC Table 16-K is taken as a category 4. If the tank is classified as being in a category 1 or category 2, the tank, supports, anchorage, and foundation shall be evaluated by a qualified Registered Professional Engineer.
