Floor design

Are you designing the floor for a school, an office, or a multi-family house?

For each application, the desired span can be selected in the drop-down menu. The required component dimensioning of LIGNATUR surface elements is displayed graphically. The floor structures shown are recommendations, tailored to the application.

Do you have any further questions? We'll be glad to advise you.

Static System – single-span beam

Ultimate limit state, serviceability limit state, and vibration design are fulfilled for all floor systems shown.

deflection w (qd) = l / 350

  • qd = (1 + kdef) ∙ (gk + ѱ1 ∙ qk)
  • creep coefficient kdef = 0.6
  • permanent load gk = g + qA
  • dead load incl. fill g
  • load of floor construction qA
  • imposed load qk = qN
  • housing qN = 2 kN/m2, ѱ1 = 0.5
  • education qN = 3 kN/m2, ѱ1 = 0.7

1. Natural frequency f1 (gk) ≥ 8.0 Hz or 8.0 Hz > f1 (gk) ≥ 5.1 Hz.
The first natural frequency is calculated only with permanent loads. Vibration acceleration a (gk) ≤ 0.1 m/s2, deflection w (F = 1 kN) ≤ 0.25 mm.
