EPB Elevated Post Base

EPB

These cast-in-place post bases provide a secure connection to the concrete and the code-required 1" standoff to help prevent rot at the post end.

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.

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).
  • Some products may be installed with the Strong-Drive® SD Structural Connector screw. See model table.

Options

12" pipe available for EPB44, 46, 66; specify "-12" after model number.

   These models are approved for installation with the Strong-Drive® SD Connector screw. See the load values below.

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 Post Capacities 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 other nail sizes and information.
