The thickness of the panel that resists load decreases with increasing nail overdriven depth.
The data show that failure load (the load corresponding to the ultimate displacement) for a joint with overdriven nail is reached at a smaller ultimate displacement than the failure load for a joint with flush-driven nail.
As compared to the ultimate displacement of joints with flush-driven nails, reductions due to overdriving were 22, 41, and 45 percent for the specimens with nails overdriven to depths of 1.
As compared to the cumulative energy dissipated by joints with flush-driven nails, reductions due to nail overdriving were 20, 40, and 44 percent joints with nails overdriven to depths of 1.
Several single nail joints were assembled with OSB structural panels and tested to determine the effects of overdriven sheathing nails on the joint capacity.
