LVL 2.0E (representative) - Design Values

LVL 2.0E (representative) is a engineered wood (lvl / psl / i-joist) grade with reference design values to Representative - see manufacturer ICC-ES / APA report. Its reference bending value Fb is 2,900 psi, compression parallel Fc is 2,900 psi, and modulus of elasticity E is 2,000,000 psi (NDS). In Eurocode 5 terms its characteristic bending strength fm,k is 48 N/mm², compression parallel fc,0,k is 38 N/mm², and mean modulus E0,mean is 13.8 kN/mm² (EN 338 / EN 14080). Values are shown before adjustment factors; apply the relevant NDS C-factors or EC5 k_mod and γ_M for your load case.

Understanding these values

For a beam in LVL 2.0E (representative), bending at Fb 2,900 psi normally sets the size, but the check that actually governs depends on the span. Short heavily loaded members are often limited by shear at Fv 285 psi, and bearing at a support is limited by compression perpendicular to grain at Fc perp 750 psi, which is the lowest of the strength values and the one most often overlooked. Used as a post or stud, the governing value is compression parallel at Fc 2,900 psi.

Stiffness for LVL 2.0E (representative) is E 2,000,000 psi, with the reduced modulus Emin 1,020,000 psi used for stability calculations such as the beam stability factor CL and the column stability factor CP. On typical floor spans, deflection rather than strength decides the section, so compare E before Fb when the member is a joist.

Under Eurocode 5 LVL 2.0E (representative) is described by characteristic values: bending fm,k 48 N/mm², shear fv,k 4.5 N/mm², compression parallel fc,0,k 38 N/mm² and perpendicular fc,90,k 6 N/mm². These are 5th-percentile figures, not allowable stresses - divide by the partial factor gamma_M (1.2 for LVL for engineered wood (lvl / psl / i-joist) under the recommended values) and multiply by k_mod for the service class and load duration, so the usable strength is materially lower than the number shown.

For LVL 2.0E (representative) the mean modulus E0,mean is 13.8 kN/mm². Characteristic density is rho,k 510 kg/m³, which is the value that drives fastener and connection capacity rather than any of the strength figures - two grades of similar bending strength can give quite different screw and dowel resistances if their densities differ.

Within the engineered wood (lvl / psl / i-joist) entries in this catalogue, LVL 2.0E (representative) is the strongest in bending at 2,900 psi, against 2,000 psi for Wood I-joist (representative) at the other end of the range.

The LVL 2.0E (representative) figures above are representative of engineered wood (LVL, PSL and I-joists) rather than of any one manufacturer's product. engineered wood (LVL, PSL and I-joists) is proprietary: published design values differ between suppliers, and for engineered products they depend on the grade stamp and the depth supplied. Use this page for scheme design and take the specific product's evaluation report for the final check.

Common questions

LVL 2.0E (representative) has a characteristic bending strength fm,k of 48 N/mm² to Representative - see manufacturer ICC-ES / APA report. This is a characteristic (5th-percentile) value, not a design strength: divide by the partial factor gamma_M and multiply by k_mod for your service class and load duration before using it in a check.

E is 2,000,000 psi, and the reduced modulus Emin used in stability calculations is 1,020,000 psi. E is what you use for deflection; Emin feeds the beam stability factor CL and column stability factor CP. On typical floor joists deflection governs, so E is usually the number that decides the section.

The mean modulus of elasticity parallel to grain E0,mean is 13.8 kN/mm². Use E0,mean for deflection under the characteristic combination.

No. The NDS figure (Fb 2,900 psi) is an allowable stress already reduced for safety, while the Eurocode value (fm,k 48 N/mm²) is a characteristic strength that still has gamma_M and k_mod to be applied. They belong to different safety formats, so converting one to the other by unit conversion alone gives a wrong answer. Design in one system throughout.

Use the characteristic density rho,k of 510 kg/m³. Fastener capacities in Eurocode 5 - dowel embedment strength, screw withdrawal, nail capacity - are functions of rho,k rather than of the bending or shear strength, which is why two grades with similar fm,k can give different connection resistances.

Use them for scheme design only. LVL 2.0E (representative) is an engineered product whose design values are set by each manufacturer's own evaluation report and vary between suppliers and layups, so the figures here are representative of the product class rather than of a specific product. Confirm against the supplier's published data before finalising.
