2. LVL STRUCTURES IN FLOORS, WALLS, ROOFS AND IN SPECIAL APPLICATIONS Figure 2.16. LVL-C panel applications in a multi-storey building. Figure 2.17. Span table of LVL 36 C and multiple-glued GLVL 36 C panel for predesign of floors supported from the ends. Calculations are according to EN 1995-1-1:2004+A1:2008 and its Finnish National Annex including floor vibrations. Permanent load is 0.4 kN/m² + panel’s own weight, imposed load is 2.0 kN/m² (category A). Service class is 1 or 2 and consequences class CC2. The support length is ≥ 45 mm. Instantaneous deflection winst ≤ L/400 and net final deflection wnet,fin ≤ L/300. γM = 1,2. Double span structures may have 0,1 – 0,3 m longer maximum span lengths. Lowest natural frequency f1 > 8 Hz and maximum deflection under 1kN point load is 0,5 - 0,8 mm depending on the span length.
