Experimental analysis of plug shear failure in timber connections with small diameter fasteners loaded parallel-to-grain

Resumen:
Timber connections with small diameter fasteners that do not go through the whole timber member (such as screws or nails). may fail in brittle or ductile ways. In order to better understand their behaviour, an experimental campaign of tests of connections with small diameter fasteners loaded parallel-to-grain has been performed. The results and analysis of this work provide further information on the role of different parameters in the brittle failure. Existing models are benchmarked against these tests.
