Timber clad

Timber structures with cladding are among the most common construction methods for houses worldwide. Whereas in North America the main timber structure may be covered in a variety of materials, in Europe and Asia timber boards are seen more frequently.

Clad timber structures are inherently light which makes them attractive for earthquake-prone areas. What is more, a properly executed cladding does ensure a cohesion of all structural elements leading to a box-like behaviour of the building.

To avoid contact with rainwater timber structures should be placed on a masonry base. Whether

this base is only a plinth or a whole ground floor the problems remains the same when taking into account earthquakes forces: To make sure that the timber structure will not slide off it must be well anchored to the the masonry structure underneath.

In many earthquake affected countries people used to build the upper floor of their houses with timber. With the widespread availability of modern building materials this wise tradition is getting lost.


The manual presented in this chapter wants to re-vitalize this construction method while putting the accent on the importance of connecting all elements properly to ensure earthquake resistance.
