Built-Up Wood Stud Column — Factored Compressive Resistance

P_r for nailed built-up stud columns.

Inputs

Stud size

Number of plies

Species group

Grade

Unsupported length L (m)

Valid range: 2.00 m to 4.00 m.

Checklist (must match table assumptions)

1. Standard term load (dead + snow / occupancy)?

2. Dry service condition?

3. No incisions / fire-retardant treatment?

4. Column pinned at both ends (K_e = 1.0)?

5. Column concentrically loaded?

Factored Resistance

Factored compressive resistance P_r

— kN

Adjust inputs and checklist to see a value.

Values are valid only when checklist items 1–4 are “Yes”. If any is “No”, the values must not be used and P_r should be calculated from the column design formula.
