PB/PBS Regular and Standoff Post Bases


Installation

View step-by-step installation instructions

The PBS features a 1" standoff height. It reduces the potential for decay at post and column ends.

Material: PB – 12 gauge; PBS – see tables.

Finish: Galvanized. Some products available in ZMAX® or HDG; see Corrosion Information.

Installation:

SD9 & SD10 Compatible

Some products may be installed with the Strong-Drive® SD Structural Connector screw -

Options: PBS available in rough sizes (except for PBS46),, Contact Simpson Strong-Tie.

Additional Corrosion Protection

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.

Table
  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) may use “Wind and SDC A&B” allowable loads.
  5. Download shall be limited by the design capacity of the post. See Post Capacities for common post allowable loads.
  6. For lateral loads for all PB models: F1 allowable = 765 lbs. F2 allowable = 1325 lbs.
  7. Designer is responsible for concrete design.
  8. 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.
  9. NAILS: 16d = 0.162" dia. x 3 1/2" long. See other nail sizes and information.

Additional Corrosion Protection

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

Table
  1. For higher downloads, solid pack grout under 1" standoff plate before installing PBS into concrete. Base download on column or concrete, according to the code.
  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. 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).
  6. Download shall be reduced where limited by the design capacity of the post. See Post Capacities for common post allowable loads.
  7. Designer is responsible for concrete design.
  8. For lateral loads for all PBS models: F1 allowable = 1165 lbs. when using nails and 230 lbs. when using bolts. F2 allowable = 835 lbs. when using either nails or bolts.
  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.
