Performance of the Nail Joints on Wood Frame Shear Walls

Abstract

The performance of two types of Chinese screw nails in connections between sheathing and wood frame was assessed using ASTM-F1575-03. Specimens were tested in groups of 10, and both parallel-to-grain and perpendicular-to-grain specimens were tested in the case of ASTM-F1676-03. It was found that the type of nail had little effect on the performance of nail joints. Finally a modified model suitable to domestic nails in two directions was established on the basis of Foschi’s exponential model. The model provides useful data on the performance of sheathing-to-lumber connections.

Experimental Study on Nail Joint Shearing Properties of Light Frame Wooden Shear Walls

“…It is because that when the loading direction was perpendicular to the stud grain, the studs were cracked apart at the nail shearing points or along the grain after the peak load. When the loading direction was parallel to the stud grain, nails went on splitting the stud along the grain to a certain distance after the peak point until studs were split in two or nails pulled off the studs, which could remain the loading force for a certain displacement [19].…”
