2. LVL STRUCTURES IN FLOORS, WALLS, ROOFS AND IN SPECIAL APPLICATIONS Calculations according to EN 1995-1-1:2004+A1:2008 and its Finnish National Annex. Service class 2, Loads: own weight of surface structure 0,20 or 0,60 kN/m2, s k = snow load on ground level 0,65, 1,5 or 2,75 kN/m2 and snow load on roof level = 0,8 ∙ sk. Wind load wk = 0,4kN/m2; maintenance load qH = 0,4 kN/m2. Point loads are not taken into account. Deflection limit at the corner overhang wnet,fin ≤ (√2∙LC)/100. Figure 2.51. Span tables of LVL-C roof corner overhang panels for predesign. Span length LC is the same parallel and perpendicular to grain of the surface veneer.
