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 on the left shows the amount of material saved when using GL 28 glued laminated timber, spruce laminated veneer lumber and BauBuche GL70 in comparison with C24 solid wood (usual con struction timber). This is based on the following assumptions: _ Use in utilisation class 1 _ Load-duration class: medium _ Consistent cross-section height of 300 mm _ Calculation according to EN / 100 % 152 / 76 % 102 / 51 % 56 / 28 % Tension f t,0 200 / 100 % 129 / 64 % 68 / 34 % 44 / 22 % E-modulus E mean 200 / 100 % 175 / 87 % 159 / 80 % 132 / 66 % Required width in mm at same load % Material consumption

2 BauBuche Comparison of BauBuche and spruce EN Sheet 5 / 19 Comparison of BauBuche and spruce glulam when used in a roof truss. Due to its greater strength and density, BauBuche allows considerably slimmer beams and less connectors for the same load. 200 N d = 300 kn, tensile splice double shear, internal steel plate, dowel pins split-proof by VGS BauBuche Beam 12 bolts ø Utilisation ratio of the bolts: 100 % A = mm 2 Comparison of fasteners of BauBuche beam and spruce glulam GL28h. Fasteners for BauBuche (beech laminated veneer lumber) must be dimensioned in compliance with section 4.2 according to EN in conjunction with EN /NA with the equations for solid wood. Further details for the dimensioning of fasteners can be found in the general technical approvals no.
