Circular Pedestal Edge Distance
1.Allowable uplift loads are calculated per ACI 318-11, Appendix D
considering cracked and uncracked concrete and are qualified
for Wind and Seismic Design Categories A & B. No further
increases allowed.
2. Edge distance is considered to be measured from the center line
of the nearest anchor bolt to the edge of concrete.
3.Tabulated anchor embedments will also achieve the maximum
lateral loads from the CPTZ table on page 57.
4.Foundation dimensions are for anchorage only. Foundation
design by others. Refer to ACI318-11.
Corner Installation
Circular Pedestal Installation
MATERIAL: EPB44A—14 gauge; others—12 gauge base
plate, 1 1⁄16" OD x 8" pipe
FINISH: EPB44A—Galvanized; all others—Simpson
Strong-Tie® gray paint (may be ordered HDG);
see Corrosion Information, pages 13-15.
INSTALLATION: • Use all specified fasteners. See General Notes.
• Allows 1" to 2 1⁄2" clearance above concrete, 2" for EPB44A.
• Post bases do not provide adequate resistance
to prevent members from rotating about the base and
therefore are not recommended for non top-supported
installations (such as fences or unbraced carports).
OPTIONS: 12" pipe available for EPB44, 46, 66;
specify “-12” after model number.
CODES: See page 12 for Code Reference Key Chart.
These products are available with additional corrosion protection.
Additional products on this page may also be available with this option,
check with Simpson Strong-Tie for details.
These products are approved for installation with the Strong-Drive ®
SD Connector screw. See page 27 for more information.

Typical EPB44A Installation
1.Loads may not be increased for short-term loading.
2.Concrete shall have a minimum compressive strength, f'c = 2500 psi.
3.Multiply Seismic and Wind ASD load values by 1.4 or 1.6 respectively to obtain
LRFD capacities.
4.In accordance with IBC Section 1613.1, detached one- and two-family dwellings in
Seismic Design Category (SDC) C may use “Wind and SDC A&B” allowable loads.
5.Download shall be reduced where limited by the design capacity of the column.
See pages 245-246 for common post allowable loads.
6.For lateral loads: F1 allowable = 815 lbs. for the EPB44A and 985 lbs. for EPB44, 46
and 66. F2 allowable = 935 lbs. for the EPB44A and 1135 lbs. for EPB44, 46 and 66.
7.Designer is responsible for concrete design.
8.For full loads, nearest concrete edge required is 4" from EPB center line.
9.Structural composite lumber columns have sides that either show the wide face or
the edges of the lumber strands/veneers known as the narrow face. Values in the
tables reflect installation into the wide face. See Technical Bulletin T-C-SCLCLM for
load reductions due to narrow face installations.
10.NAILS: 16d = 0.162" dia. x 3 1⁄2" long. See pages 22-23 for other nail sizes and information.
