Figure 2.11.
Span and capacity table of LVL 48 P main beams for predesign of floor structures. Calculations according to EN 1995-1-
1:2004+A1:2008 and its Finnish National Annex. The permanent load is 20% of the characteristic load kN/m
2
. The service class is 1 or 2 and
the consequences class is CC2. The rafter has lateral torsional buckling supports on the top surface with spacing ≤ 600 mm and the loads are
located at the lateral torsional buckling supports. The support length shall be calculated separately. The initial deflection w
inst
≤ L/400 and net
final deflection w
net,fin
≤ L/300. γ
M
= 1.2. The table does not replace project-specific structural design. Double beams are calculated as separate
beams in lateral torsional buckling.
