Beam BauBuche GL75

The superior strength and stiffness of BauBuche allows smaller cross-sections, which in turn means major savings in material consumption. The dimensioning of a structure is determined by various properties, depending on the particular application. In the case of single-span beams, deformation (stiffness) is generally the key factor, whereas with continuous beams, it is bending strength or shear strength; and with columns and frameworks, it is compressive and tensile strength. The table opposite shows the amount of material saved by using GL28 glued laminated timber, spruce laminated veneer lumber and BauBuche GL75 respectively, in comparison with C24 solid wood (normal construction timber).

This is based on the following assumptions:

• Use in service class 1
• Load-duration class: medium-term
• Uniform cross-sectional height of 300 mm
• Calculation according to EN 1995-1-1.
