Values
LIGNATUR elements are CE-labelled and can be calculated according to the European Technical Approval ETA-11 / 0137, the Eurocode and the national standards. Precise analysis of LIGNATUR elements for single-span girders and multi-span girders is limited to checking the moments, lateral forces and deflections. The following tables show the characteristic data of LIGNATUR elements.

After selecting from the dropdown menu, the calculated characteristic values will be displayed. The formulas used can be found in the “Übersicht Formeln”. The resistance values are calculated based on wood strength class C24 according to ETA 11/0137.
The visualization of your selection is simplified and does not consider the element height or the acoustic type..

Single-span beam Calculator
Use the characteristic values determined above to calculate the maximum span. We recommend the following maximum initial deflection values: ≥ l/475 for maximum deflection in the case of multi-family houses, school buildings and office ceilings with floor structures = 200 kg/m2, for gallery ceilings without additional structures and single-family homes with light dry-build superstructures ≥ l/600, for accessible roofs ≥ l/500 and for flat roofs ≥ l/400.

Dlubal Datenbank
The Dlubal structural analysis program offers many LIGNATUR characteristic values in its database for the structural design of our LIGNATUR ceiling and roof elements. Thank you for including LIGNATUR in the Dlubal database.
Static reinforcement
For structural reinforcement the LIGNATUR elements may be partially fabricated in solid timber.
