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. |
