2. LVL STRUCTURES IN FLOORS, WALLS, ROOFS AND IN SPECIAL APPLICATIONS Figure 2.8. Maximum span lengths of LVL 48 P floor joists for predesign of compartment floors. 2,0 kN/m2 live load, 0,3 kN/m2 partition load and 1,6 kN/m2 self-weight including a 50 mm screed in addition to the LVL members. The basic option has c/c400 mm joist spacing, 22 mm chipboard decking without gluing and no transverse bracings. In advanced option has transverse bracing, glued decking and 45x45 mm c/c 400 mm cross batten underneath the joists. Lowest natural frequency f1 > 8 Hz and maximum deflection under 1kN point load is 0,5 - 0,8 mm depending on the span length (FI NA requirement for EN1995-1-1).
