Dissertation report
Cross laminated timber representing the modern
format of solid timber construction, came as a result of
sawmills overproduction of low-grade wood and the
industry’s ambition to pose a solution for wood in
multi-storey structures.

Panels must be laid down during
transportation and flipped to upright
position from truck during assembly.
Flipping of panels may be hazardous in
regards to shear loading of lifting screws.
Requires more individual lifts and time in
regards to jointing.
Wall height not exceeding 2,95 m
≤2,95m
Transport limitations:
Height: 3,0 m
Width: 2,40 m
Length: 13,5 m
Panels can be transported vertically and
requires no flipping during assembly.
Using wall panel of ex. 2,95 m will result in
reduced waste and work-flows in the factory
and on site.

CLT slabs used in functions such as floor slabs exposed to live
loads, are in terms of span length primarily limited by vibration
criteria's which are difficult to satisfy in span lengths ≥ 6 – 6,5 m.

In functions where not exposed to live load, the SLS + ULS
criteria's can be met in spans up an approximate 8,0 m.

2. Analysis of sound performance requirements
On the basis of experiences gained in solid
timber project such as Limnologen,
Sweden 2009, the acoustic climate
showed to be challenged by sound waves
under the normal frames of frequency.
Provided the issues with light-buildings
and transfer of sound, the building must
fulfil sound class B which is added the
spectral correlation Rw C 50-3150.
