Timber Ceilings with insufficient load bearing capacity

You feel sure that floor will still support  the new aquarium when it has been filled with water? You probably have already checked with a statics engineer. Does that apply to  the filled bath tub and the new Concert Grand as well?

In Ergänzung der EC 5 »Bemessung und Konstruktion von Holzbauten« soll der HBV genormt werden. In Vorbereitung hierauf arbeiten mehrere Forschungseinrichtungen in Europa zur Zeit an einer Technical Specification.

Eigenschaften des HBV

  • große Spannweiten
  • geringes Eigengewicht
  • guter Feuerwiderstand
  • guter Schallschutz
  • geringe Schwingungsanfälligkeit
  • Vorfertigung möglich

Despite the increased mass, the ceiling may now need to support twice or three times as much as before.

Insufficient load bearing capacity is frequently the reason for the need to refurbish a ceiling. The mass needed for the strengthening (repair) or refurbishment of timber-beamed ceilings to comply with  sound attenuation and fire prevention requirements has the beneficial side effect that a distinct increase in the load bearing capacity is achieved.

The concrete in the composite structure increases the net supported load on the Elascon standard TCC variant - with the concrete superimposed on the ceiling - by a factor of 3. Whereas the ceiling was previously able to support some 200 kg per square metre, the finished  timber-concrete composite ceiling will now support 600 kg per square metre - and that despite the fact that approx. 150 kg loading per square metre has been introduced.

Simple preliminary pre-dimensioning will ensure that the final decision will be sound.

Even with the variant Elascon TCC flat you will actually achieve double the load bearing capacity! And when it is really important that single loads - e.g., roof loads, linear, block or trapezoidal loads are safely  taken up, the TCC Composite ceilings offer an unbeatable solution. So, why not use our free-of-charge preliminary assessment service which will show whether a Timber-Concrete composite ceiling will produce the required result and becomes an option for you to consider! We will happily offer various sizing options to the planner of your own TCC composite supporting structure for the establishment of the sizing sand the planning of the works.
