Wall bracing test results on 4.5 mm plywood sheathed, JD5 and JD6 pine framed wall panels for Dindas Lew Pty. Ltd.

"Two 2.4 m high x 2.7 m long wall frames consisting of 70 x 35 mm studs at 450 centres and 70 x 45 mm top and bottom plates were constructed from F5 pine. One panel was of Spruce Pine Fir with a joint strength group JD5, the other was Hem Fir of joint strength group JD6. Each frame was sheathed on one side only using 4.5 mm thick, F11 D/D structural grade plywood. Sheathing connectors were 2.8 mm diameter x 30 mm long galvanised clouts hand driven at 150 mm centres around edges and 300 mm centres on internal studs. Panels were tested in racking, the plywood was then stripped, the frames reversed and resheathed and the panels retested in racking."--p. (ii)
