Tech Note - LVL-21 - Versa-Lam LVL 1.8E 2650 Large Columns: Allowable Axial Load Table
Notes:
1. Table assumes that the column is braced at column ends only (in each direction). Effective column
length is equal to actual column length.
2. Allowable loads are based upon one-piece (solid) column members used in dry service conditions. BC
Calc® sizing software (www.BCCalc.com) may be used for multi-piece column design.
3. Allowable loads are based on an eccentricity value equal to 0.167 multiplied by either the column
thickness or width (worst case).
4. Allowable loads are based on axial loaded columns using the design provisions of the 2024 National
Design Specification (NDS) for Wood Construction. Table capacity values based upon a buckling length
coefficient, Ke equal to 1.0 (rotation free, translation fixed at each column end per NDS Appendix G). A
Ke coefficient of 1.0 conservatively models typical wood column applications. For other end
conditions, contact Boise Cascade EWP Engineering. For side or other combined bending and axial
design, see provisions in 2024 NDS.
5. Lateral loads (wind loading) are not considered in this table. BC Calc® sizing software
(www.BCCalc.com) may be used for out of plane lateral load column application design.
Reference Design Values:
• Modulus of Elasticity (Eₜ) (True / Shear Free) = 1.8 x 10⁶ lb/in²
• Modulus of Elasticity (Eₐ) (Apparent) = 1.7 x 10⁶ lb/in²
• Modulus of Elasticity (Eₘᵢₙ) (Lateral Stability) = 0.9 x 10⁶ lb/in²
• Flexural Stress (Fᵦ∥) (Parallel to Gluelines) = 2650 lb/in²
• Flexural Stress (Fᵦ⊥) (Perpendicular to Gluelines) = 2400 lb/in²
• Compression Parallel to Grain (F𝚌∥) = 3000 lb/in²
• Compression Perpendicular to Grain (F𝚌⊥) (Parallel to Gluelines) = 750 lb/in²
• Compression Perpendicular to Grain (F𝚌⊥) (Parallel to Gluelines) = 610 lb/in²
