Brittle failures should be avoided in timber structures because they engender unpredictable collapse in case of cyclic plastic deformations such as during earthquakes. In such cases, ductile failures should be promoted as they allow a redistribution of the load, enabling the building to remain standing. Intrinsically, wood is a brittle material. Ductility can be achieved in timber structures through connections using mechanical fasteners made out of steel. This study contributes by investigating the modes of failure of multiple-nail steel-to-timber connections loaded parallel to the grain in case of New Zealand Radiata Pine solid timber.
