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. 58 Model No. W EPB44A EPB44 EPB46 EPB66 3 9⁄16 3 9⁄16 5 1⁄2 5 1⁄2 EPB44A EPB44 EPB46 EPB66 3 9⁄16 3 9⁄16 5 1⁄2 5 1⁄2 Allowable Loads (160) Non- Cracked L H Nails Cracked Download Uplift Uplift Wind and Seismic Design Category A & B 3 2 3⁄8 8-16d 1120 785 2670 3 1⁄4 2 5⁄16 8-16d 1035 725 3465 3 5⁄16 3 12-16d 1035 725 3465 5 1⁄2 3 12-16d 1035 725 3465 Seismic Design Category C-F 3 2 3⁄8 8-16d 940 660 2670 3 1⁄4 2 5⁄16 8-16d 870 605 3465 3 5⁄16 3 12-16d 870 605 3465 5 1⁄2 3 12-16d 870 605 3465 Pilot Hole (Typ.)

I28, F1, L27 I28, F1, L27 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. C-C-2015 © 2015 SIMPSON STRONG-TIE COMPANY INC. PRINTED 12/14 EPB Elevated Post Bases
