2.4.2 Multiple-glued GLVL columns

Multiple-glued GLVL can be used in larger cross sections for

load-bearing columns in post and beam structures. They are

glued together from several LVL-P or, in some cases, LVL-C

laminas. The column cross sections can be tailored project-spe-

cifically, but for optimized material efficiency the standard

widths or 5-10 mm smaller widths are recommended. Column

thicknesses are derived from multiple sanded LVL laminas.

• Recommended column thicknesses: 84, 90, 96, 108, 120, 133

and 144 mm

• Recommended column widths: 200, 225, 240, 260, 300, 360,

450 and 600 mm

Massive multiple-glued GLVL columns are possible for

heavy-duty structures up to glulam beam dimensions. The

maximum width is usually 400 mm, but the thickness can be

up to 2000 mm. In visible applications, massive multiple-glued

GLVL cross sections have the advantage that they are not sensi-

tive to cracking in dry conditions. However, for visible applica-

tions the sanding and lamina specifications must be separately

agreed with the supplier to ensure clean veneer surfaces.
