2. LVL STRUCTURES IN FLOORS, WALLS, ROOFS AND IN SPECIAL APPLICATIONS Figure 2.11. Span and capacity table of LVL 48 P main beams for predesign of floor structures. Calculations according to EN 1995-11:2004+A1:2008 and its Finnish National Annex. The permanent load is 20% of the characteristic load kN/m2. 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 winst ≤ L/400 and net final deflection wnet,fin ≤ L/300. γM = 1.2. The table does not replace project-specific structural design. Double beams are calculated as separate beams in lateral torsional buckling. 0 5 10 15 20 25 30 35 40 1,5 2,0 2,5 3,0 3,5 4,0 4,5 Characterastic load [kN/m] Maximum span length [m] LVL 48 P main beams h = 200 - 300mm for floors 45x200 45x240 45x260 45x300 75x200 75x300 2x45x200 2x45x240 2x45x260 2x45x300 0 5 10 15 20 25 30 35 40 45 50 2,0 2,5 3,0 3,5 4,0 4,5 5,0 5,5 6,0 6,5 7,0 Characterastic load [kN/m] Maximum span length [m] LVL 48 P main beams h = 360 - 600mm for floors 45x360 51x400 63x500 75x600 2x45x360 2x51x400 8,0 Floor main beams 0 5 10 15 20 25 30 35 40 1,5 2,0 2,5 3,0 3,5 4,0 4,5 Characterastic load [kN/m] Maximum span length [m] LVL 48 P main beams h = 200 - 300mm for floors 45x200 45x240 45x260 45x300 75x200 75x300 2x45x200 2x45x240 2x45x260 2x45x300 0 5 10 15 20 25 30 35 40 45 50 2,0 2,5 3,0 3,5 4,0 4,5 5,0 5,5 6,0 6,5 7,0 Characterastic load [kN/m] Maximum span length [m] LVL 48 P main beams h = 360 - 600mm for floors 45x360 51x400 63x500 75x600 2x45x360 2x51x400 LVL Handbook Europe 57
