H 20 Beam Charachteristics

Wood species

Spruce

Wood moisture

12 % +/- 2 % at delivery Weight: 4.5 kg/m

Glue

Melamine resin based adhesive, adhesive type I EN 301 – approved for use with load bearing timber components

Surface protection

Water repellent colour glaze is used to ensure the beam is waterproof

Chord

Made of carefully selected spruce wood; Finger-jointed, solid wood cross-sections, dimensions 80 x 40 mm; Fingerjointed chords; Web-milling on the opposing side of the core (left-sided chord surface); Planned and chamfered to app. 0.4 mm

Web

3-ply solid wood panel, laminated, vertical growth-ring orientation

Surface protection

The entire beam is treated with a water-resistant colour stain

Fact sheet

Dimension Value (a) Tolerance (b)
Beam height 200 mm ± 2 mm
Chord height 40 mm ± 0,6 mm
Chord width 80 mm + 0,8 mm/-1,2 mm
Web thickness 28 mm ± 1 mm

Characteristic Limits – values apply at a wood moisture content of 12 % ± 2%

 

Strains Permissible stress values Characteristic limits of load-bearing capacity
Shearing force ZUL Q = 11,0 kN Vk = 23.9 kN
Bending moment ZUL M = 5,0 kNm Mk = 10.9 kNm
Support Rb,k = 47.8 kN
Section modulus Wx= 461 cm3
Geometrical moment of inertia Ix= 4.613 cm4
Elasticity modulus E = 10.000 N / mm2
Shearing modulus G = 600 N / mm2

The values of the section modulus and the geometrical moment of inertia apply to new or used concrete formwork beams. An analogously increased factor of safety needs to be added for severely worn beams.
