Ten joints with flush-driven nails and 10 joints for each overdriven nail depth (1.6, 3.2, and 4.8 mm) were assembled.
Three joints with flush-driven nails, one joint with 3.2 mm overdriven nail, and two joints with 4.8 mm overdriven nails did not fail.
Only 20 percent of the joints with flush-driven nails and 20 percent of joints with 1.6 mm overdriven nails failed due to low-cycle fatigue.
peak load of joints decreases with increasing overdriven nail depth;
Stiffness increased 9,20, and 21 percent for joints with cooler nails overdriven 1/16, 1/8, and 3/16 inch, respectively, compared to the stiffness of joints flush driven with cooler nails.
Joints with cooler nails overdriven 1/16 inch and 1/8 inch do not experience any reduction in strength, while joints overdriven 3/16 inch exhibit an approximately 12 percent reduction in strength.
The theoretical strength is reasonably close to the measured strength for joints flush driven or overdriven 3/16 inch.
The data indicate that ultimate loads are reached at smaller critical displacements for joints overdriven with cooler nails compared to joints flush driven with cooler nails.
