13000 Tendon Prestressed Concrete Circular Tank 13000-4
Revised March 27, 2010

7. Roof Snow Load = N/A
1.10 FOUNDATION/FLOOR DESIGN
A. Dead Loads.
B. Water Loads.
C. Uplift due to ground water.
D. Radial forces from base to tank wall.
E. Tank foundations shall be designed for an allowable soil bearing pressure of 2,500 psf
after compaction.
F. Tanks shall be supported on suitable natural soils, and/or on new compacted structural
fill.
G. When tanks are to be installed in locations susceptible to frost, the foundations shall
extend below grade to the maximum frost depth for the area.
H. Floor shall be membrane type.
I. Loads are assumed to be transmitted to the sub -base directly through the membrane.
Minimum thickness of the membrane slab shall be 5 inches. Floors shall be placed
continuously in sections as large as practicable to decrease the length of construction
joints and their related problems. Precautions shall be taken with large floor sections to
limit long-term shrinkage by using low -slump concrete, adequate reinforcement, and
proper curing conditions. Hydrostatic uplift when the tank is empty, or when the tank
water level is lowered rapidly, shall be precluded by adequate surface drainage and
under drainage, if necessary.
J. Where joints are provided, suitable methods and/or devices will be employed to prevent
leakage. For crack control in the floor, the minimum reinforcement in each of the two
perpendicular directions in the horizontal plan shall be .0015 times the cross sectional
area of the concrete area for pre -stressed floors or .005 times the cross sectional area for
non -pre -stressed floors. Where the wall base shear is transferred into radial tension in
the slab, additional reinforcement shall be as required. A minimum of 1 1/2 in. of concrete
protection shall be provided for all reinforcing steel on the sides of the walls in contact
with the liquid contents of the tanks.
K. Pre -stressed floors shall also be designed to produce a minimum residual compressive •
stress of 200 psi (1.4 MPa) after allowance for slab -sub -grade friction and tensile forces
resulting from the wall base reaction. Slab -sub -grade friction and the friction coefficient
shall be in accordance with "Post -Tensioned Commercial and Industrial Floors" of the
Post Tensioning Institute for Type II slabs. The pre -stressed floor tendons shall be
stressed in two stages: one half stress in each tendon within three days after placement
or earlier, if the strength of the concrete has reached 1500 psi (11 MPa), and full stress in
each tendon within 10 days if the strength of the concrete has reached 3000 psi. (21
MPa).
L. The sub -grade for membrane floors shall have adequate bearing capacity to sustain the
weight of the tank, fluid contents, and roof load. The floor slab shall not be constructed
directly on the natural sub -grade soil or rock, unless it is uniform and compact.
13000 Tendon Prestressed Concrete Circular Tank 13000-5
Revised March 27, 2010

1.11 FOOTING
A. Wall Footings:
1. A continuously reinforced concrete footing, either as a thickened floor edge region or
one separated from the floor, shall be provided to distribute the vertical loads at the
base of the wall to the underlying foundation material. Foundation for membrane
floors and footings shall be of uniform compaction and bearing value to support the
structure without differential settlement that may damage the structure. Foundation
for footings shall likewise provide uniform support to limit differential settlement.
B. Column Footings:
1. Column footings shall be provided to support both vertical live and dead loads and
may be an integral part of the membrane floor. Separation of the column footing from
the floor requires the use of submerged joints that increase the potential for leakage.
Where footings are placed below the floor slab, and integral with it, additional
reinforcing shall be required to control cracking due to restriction of slab movement
during curing and temperature or moisture changes. Inverted footings above the slab
avoid this condition but may entrap sediment and impede normal wash down and
cleaning maintenance. Transitions in floor thickness should be gradual, and
additionally reinforced to prevent shrinkage cracking and leakage.
1.12 COLUMNS AND BEAMS (IF REQUIRED)
A. Columns and beams shall conform to the requirements of ACI 318, including
supplements thereto. Minimum concrete cover over principal reinforcement shall be 2-
inches (50 mm).
1.13 WALL DESIGN LOADS
A. Internal Pressure: The pressure from maximum water level to the top of the floor slab.
B. Backfill Loading: The lateral pressure from earth backfill, symmetrical or asymmetrical.
Net lateral loads, including those due to unequal backfill, shall be determined by rational
methods of soil mechanics based on foundation and soils investigations. Surcharge loads
on backfill surfaces shall be considered. Backfill pressure shall not be used to reduce the
amount of post -tensioning force required for resisting internal water pressure. The
assumed internal friction angle of the soil shall be no more than 20 degrees for unit soil
density of 125 pounds per cubic feet. Hydrostatic pressure shall be considered unless the
design ground water elevation is below the bottom of the tank foundation.
C. Consider all effects of construction including loads resulting from equipment, materials,
and construction methods to be used.
D. Appurtenance loads.
E. Operating loads and system surges.
F. Compressive stresses and bending moments in the wall due to application and post -
tensioning forces.
G. Temperature gradient through the wall.
H. Moisture gradient through the wall.
13000 Tendon Prestressed Concrete Circular Tank 13000-6
Revised March 27, 2010

I. Seismic loads- shall be as required by AMSI A58.1

1. Dead loads including sustained surcharges
2. Earth loads
3. Snow loads
4. Live loads- 20 psf
5. Appurtenance loads
6. Operational loads
7. Temperature stresses
M. The minimum final circumferential pre -stressing force to contain the water load at any
point on the wall, including the allowance for a minimum residual compression of 200 psi
in the core wall is:
Pfw= (0.063 x R x H) + (28.8 x tc) (P in kips/ft of height, unit water kips/cf,
other units in ft).
N. Allowance for stress losses and stresses due to temperature and moisture gradients shall
be made in determining the circumferential pre -stressing required. For an empty open -top
tank the minimum final horizontal pre -stress, post -tensioning force, after losses, shall
provide 200 psi compression in the concrete core wall at any point on the wall when free
joints are assumed at the top and bottom.
1 14 VERTICAL STRESSES AND REINFORCEMENT
A. Maximum tensile stress for regular mild steel reinforcement used to resist vertical
bending stresses shall be 18,000 psi for Grade 60. Bar size shall be no greater than #8
and bar spacing shall not exceed 12 inches.
B. Shear Forces: Reinforcement of joints must be sufficient to resist the following loads and
any combination thereof:
1. Water
2. Backfill
3. Pre -stressing
4. Other conditions specific to the site
C. Reinforcing steel should not be credited with resisting any portion of primary
circumferential tension resulting from radial design pressure.
13000 Tendon Prestressed Concrete Circular Tank 13000-7
Revised March 27, 2010

D. Mild steel reinforcement shall not be used to resist any portion of circumferential tension.
1.15 POST -TENSIONING STEEL
A. Maximum permissible initial stress f in any wire on the wall shall not exceed 0.75fpu.
B. Allowance for stress losses in steel, and for maintaining residual compression in the
concrete if not calculated by more precise means, should assumed as 32,000 psi. This
figure includes consideration of losses due to shrinkage, plastic and elastic shortening of
concrete, and relaxation of steel. A greater allowance for stress losses may be required
for structures subjected to unusual creep, shrinkage, or temperatures, or where the radial
design pressure is not applied for a long time after completion of construction.
C. Friction losses should be computed in accordance with ACI 318 and should be added to
other computed losses.

after deduction of the above allowances for stress losses, shall not exceed 0.60 fpu.
1.16 NONSTRESSED REINFORCEMENT
A. Reinforcing steel shall be designed in accordance with the requirements of ACI 318-86
(Ultimate Strength Design Method with ACI 360 Modified Load factors). Maximum crack
control quantity for deformed bars provided in ACI 350 shall not be exceeded.
B. Reinforcing may consist of bars or welded wire fabric to effectively control cracking due to
bending moments in the wall.
C. Reinforcing steel should not be credited with resisting any portion of primary
circumferential tension resulting from radial design pressure.

PART 3 - EXECUTION
3.1 CONCRETE PLACEMENT
A. Unless specifically authorized in writing, concrete shall not be placed during cold weather
when the ambient temperature is below 35 degrees F and rising, or below 40 degrees F
and falling, when the concrete is likely to be subjected to freezing temperature before
final set has occurred and the concrete strength has reached 500 psi. Most well
proportioned concrete will reach this strength when the temperature has been maintained
at 50 degrees F into the second day after placement. The materials shall be heated so
that the temperature of the concrete when deposited shall be not less than 50 degrees F,
or as otherwise specified in ACI 306, or more than 90 degrees F. If required, all methods
and equipment for heating and protecting concrete -in -place shall be subject to approval.
B. For concrete placed during extremely hot weather, the aggregate shall be cooled by
frequent spraying in such a manner as to utilize the cooling effect of evaporation. During
such periods, the placement schedule shall be arranged, as approved, in such manner as
to provide time for the temperature of the previously placed course to recede. The mixing
water shall be the coolest available at the site, insofar as is practicable and shall conform
to ACI 305.
C. Placement of concrete during periods of low humidity shall be avoided when feasible and
economically possible, particularly when large surface areas are to be finished. In any
event, surfaces exposed to drying wind shall be covered with polyethylene sheets
immediately after finishing and shall be water cured continuously from the time the
concrete has taken initial set. Curing compounds may be used in conjunction with water
curing.
D. Concrete for each precast panel shall be placed in one continuous operation.
E. Precast tank supplier shall provide for all penetrations and openings in the tank walls, as
indicated on the Drawings,and subject to Engineer's approval.
3.2 ERECTION
A. The precast panels shall be erected to the correct vertical and circumferential alignment.
The edges of adjoining panels shall not vary inwardly or outwardly: from one another by
more than 3/8 inch (9.5 mm) and shall be placed to the tank radius, within 'the same
tolerance. Tank wall penetrations and openings shall be in proper alignment and location.
B. The vertical slots between panels shall be filled with cast -in -place, concrete, compatible
with the details of the joint. The strength of the concrete grout shall. be at least equal to
that specified for concrete in the wall panels.
C. The steel reinforcement shall be placed in conformance with ACI 301. The minimum
cover over steel and welded wire fabric reinforcement shall be as specified.
D. Set braces with wedge anchor type inserts into the tank bottom at the correct radial
position.

E. Erect panels on low friction bearing pads, remove the lifting attachments and plumb the
panel.
F. Threading the circumferential tendons should begin after all panels are erected and
plumbed. Pointing the strand ends with a grinder and/or use of lubricant between the
strand and chases may be necessary if misalignment exists.
G. Vertical joints must be formed and air entrained concrete placed in them. Concrete must
be without voids. Aggregate segregation must not occur. Test cylinders must be made,
cured under job site conditions, and broken to determine when circumferential post -
tensioning may proceed.
H. After post -tensioning is complete and the elongations are checked by the Engineer, the
excess strand length may be removed and the anchorage hardware and exposed wire
strands shall be completely coated with epoxy or encapsulated in plastic. The anchorage -
coupler area shall then be covered with the required concrete cover (as per
manufacturer's design) and the void inside the cover shall be grouted solid with concrete
grout.
Grouting of tendon ducts should be carried out as promptly as possible after tensioning.
The total time the pre -stressing steel is exposed to other than a controlled environment
prior to grouting shall not exceed 10 days, nor 7 days after tensioning, whichever is less,
unless special precautions, such as use of a vapor phase corrosive inhibitor, are taken to
protect the pre -stressing steel. The methods or products used shall not jeopardize the
effectiveness of the grout as a corrosion inhibitor, nor the bond between the pre -stressed
reinforcement and grout. Vapor phase corrosion inhibitors should be used in strict
accordance with the manufacturer's recommendations. Additional restrictions may be
appropriate for potentially corrosive environments.
J. Grouting equipment shall be capable of grouting at a pressure of 200 psi (1.4 MPa).
However the tendon ducts should not be over pressurized during injection if blockage
exists. Instead the grout should be washed out and the blockage removed. Ducts may be
flushed with clean water (not air) prior to grouting to assure there are no blockages.
K. Horizontal grouted tendons shall have air release valves which will also act as standpipes
at intentionally high points and drains at intentionally low points such as when tendons
are deflected around penetrations. These vents and drains, and a vent at the opposite
end of the tendon from the point of injection, should be closed when a steady stream of
pure grout is ejecting. After all vents and drains are closed, the pressure in the duct can
be increased to 100 psi (0.7 MPa) and a valve at the injection end closed to lock off the
grout under pressure. After grout has set, but not less than 24 h after grouting, cut off any
vents or stand pipes and seal.
L. Grout injections in vertical tendons shall always be from the lowest point in the tendon to
avoid entrapping air.
M. A thixotropic admixture shall be used to prevent bleeding and grout settlement in the
horizontal tendons.
N. All cement grout should pass through a screen with 0.125 in. (3 mm) maximum" clear
openings prior to being introduced into the grout pump. -
O. When quick setting can occur due to hot weather, the grout should be cooled by
acceptable methods such as cooling the mixing water to prevent blockages during
pumping operations. When freezing weather conditions prevail during and following the
placement of grout, adequate means, such as keeping the wall temperature up by
13000 Tendon Prestressed Concrete Circular Tank 13000-12
Revised March 27, 2010

heaters or blankets, shall be provided to protect the grout in the ducts from freezing until
the grout attains a minimum strength of 1000 psi (6.9 MPa).
P. The seal between the walls and tank bottom is then installed. The concrete must be dry
and have a moisture content of less than 5% for seal installation. Temperature must be
50 degrees F (min.). After the seal is installed and cured, the tank should be hydrotested.
3.3 WALL TOLERANCES
A. The maximum out -of -round tolerance for precast concrete panel walls shall be based on
the ratio of +/- 1/2 in. per 100 feet diameter circle and the circumference shall be a
smooth curve. Tolerance in wall thickness shall be + 1/4 inch concrete wall thickness and
shall not be less than specified. All transitions shall be gradual and smooth. Walls shall
be plumb within a tolerance not exceeding 3/8 in. per 10 ft. of vertical dimensions.
3.4 ELASTOMERIC BEARING PADS
A. Where bearing pads are used, the tank wall shall be free of all obstruction that would
prevent free movement of the joint. All bearing pads shall be placed at a minimum of 12
inches from panel's vertical edges toward panel centerline.
B. Material for the pads shall conform to ASTM D2000 at locations indicated on the
reviewed shop drawings.
3.5 MANHOLES, LADDERS, HATCH COVERS, OVERFLOWS AND OTHER ACCESSORIES

under this section.
B. Wherever aluminum is installed in contact with dissimilar metal, concrete, or masonry,. the
aluminum shall be painted with a heavy coat of bitumastic paint or separated with butyl
tape. Adequate protection shall be provided during fabrication, shipment, site storage,
and erection to prevent damage to finish work. Aluminum work shall be cleaned before
acceptance, removing all blemishes, finger marks, oxidation, etc., and left in first-class
condition. Cleaning compound shall be approved by the aluminum manufacturer.
