Kielsteg - defining the design parameters for a lightweigth wooden product

Andreas Trummer, Stefan Krestel

Research output: Contribution to conference(Old data) Lecture or Presentation


The submitted abstract presents results of a successful building product development for a lightweight load carrying roof- and floor element made of timber. The so called Kielsteg-Element is made for covering large areas and is characterized by its distinctive cross section. Sawn wooden upper and lower surfaces are kept apart using thin wooden plates. This cross section design allows an enormous flexibility for the effective depth which in turn results in spans from 6.0 to 27.0 meters. High demands on craftsmanship and optical quality open a wide range of use.
