Technical Note: Lateral Connections and Withdrawal Capacity of Western Juniper

Hayley Morris, Arijit Sinha, Byrne T Miyamoto

Abstract


The goal of this project is to increase the amount of available information about western juniper wood to encourage its use in structural applications. This project evaluated the performance of connections involving western juniper wood and other common wood-based building materials. The tests for this project included edge lateral nail connection tests (ASTM 2007a), dowel bearing strength tests (ASTM 2007c), and withdrawal tests (ASTM 2007b). The performance of juniper and juniper-oriented strand board (OSB) connections were characterized. The results were also evaluated against predictive design equations found in the National Design Specification (NDS). The data obtained in this study suggest that NDS equations conservatively predict the load-carrying capacity of a juniper-OSB connection but consistently predict the failure mode.
