2. LVL STRUCTURES IN FLOORS, WALLS, ROOFS AND IN SPECIAL APPLICATIONS
Figure 2.64.
LVL-P integrated rim beam for timber frame wall structures. The bracing and load-bearing beam fits the thickness of timber-frame
walls. Key benefit: More possibilities for opening positioning with fewer load-bearing columns.
Calculations according to
EN 1995-1-1:2004+A1:2008 and its
Finnish National Annex. Permanent
load is 25% of total characteristic load,
the remainder is snow load. Wind load
not accounted for. Service class 1 or 2;
consequences class CC2. The beam has
lateral torsional buckling supports on
the top surface at ≤ 600 mm spacing.
Support length to be calculated
separately. Net final deflection
