Shear walls using nailed sheathing panels and wood framing form an important lateral force resisting system in wood structures. During construction of wood shear walls, however, it is common for nails to be overdriven. Overdriven driven nails may significantly reduce the shear wall strength. The objective of this paper is to determine if the reduction in shear wall strength is proportional to the nail-head depth by idealizing load-displacement curves for sheathing connections with overdriven nails, and employing the idealized load-displacement curves in a analytical model to predict the strength of shear walls with various nail-head depths.
