In design codes, nail spacing are mainly determined to avoid splitting during nailing. In case of predrilled holes, and steel-to-timber connections increased nail density is allowed. This may lead to the exceeding of the timber capacity in the joint area, and to the unfavorable brittle block tearing failure with reduced capacity. The first models to predict the brittle behavior of nailed joints has been based on the principle of reducing the effecting number of nails after a changing point. A model presented by Kangas et al. (1996) suggests that the capacity of a nailed connection with given nail spacings and distances depends on the nail capacities up to a certain joint length, after which the block tearing failure can occur. The capacity of the joint is limited by the sum of the nail capacities and by the sum of the tensile and shear capacities of timber in the joint area.
