Abstract:The joint-slip in nailed joints in the form of standard block shear specimens was measured with the aid of a small apparatus which can be fixed directly to the specimen.

The method of measuring joint-slip of nailed joints as described in this paper yielded very accurate and satisfactory results. The load-displacement curves obtained are very typical for nailed joints.

The deformation registered by the Instron testing machine did not represent the true joint-slip, but rather the total deformation which took place in the wood as well as the machine parts.
Keywords:Photosynthetic rate  Transpiration rate  Ocotea bullata
