Compression Post Recommendations

Asymmetrical Posts: This arrangement means using a maximum of three built-up studs at the end of the wall and multiple number of studs at the opposite side of the Strong-Rod. This provides uniform anchor placement and consistent end-of-wall placement location at upper floor levels.

Asymmetrical Posts
Asymetrical Post Diagram

Estimate of Moment Arm = wall length - total no. of studs at the end of wall - rod space (9" max) - 3"

Nailing Example: (4) total closest compression members adjacent to rod: 2" o.c. edge nailing x 4 = 8" o.c. nailing to two closest studs, each side of rod.

Asymmetrical Compression Posts (Multiple 2x Members) Perpendicular and Parallel to Grain Factored Resistance for D.Fir-L

C-L-SRSCAN18-PG-32-A
  1. Lumber based on 2x_ D.Fir-L No.1/No.2 grade. See General Notes for additional information.
  2. COG = Centre of Gravity of Compression End
General Notes
  1. Bearing loads are perpendicular-to-grain values and include bearing factor KB and size factor KZCP.
  2. Perpendicular- and parallel-to-grain values include KD = 1.15 load increase.
  3. Calculations based on Ke = 1.0 for parallel-to-grain resistance in depth direction of stud.
  4. Calculations assume KH = 1.10 with wall sheathing providing lateral restraint against buckling in 38 mm direction of stud.
  5. Fastening of studs to wall sheathing and wall sheathing specifications to be provided by Design Professional, not by Simpson Strong-Tie.
