Title: Lateral and tensile resistances of glued face-to-face and end-to-face joints in pine plywood and oriented strandboard
Description:
This study investigated the lateral shear and tensile load resistances of glued face-to-face and end-to-face joints in southern yellow pine plywood and oriented strandboard (OSB). Face-to-face joint test results indicated that glued plywood joints had more resistances to shear and tensile loads than OSB joints, and tested joints constructed in both the plywood and OSB showed significantly higher lateral shear load resistance than tensile load resistance. The face grain orientation of joint members had a significant effect on the load resistances of plywood joints, but not on OSB joints. End-to-face joint strength evaluation showed that tested joints had significantly higher lateral shear load resistance than tensile load resistance, and the resistances of plywood joints to shear and tension loads were statistically higher than those of OSB joints. The wax on OSB surfaces tended to weaken joint load resistances.
