Tensile, moment, and torsional resistance evaluation and prediction of mortise-and-tenon joints in wood-based composites.

【摘要】This study was performed to characterize and understand static loading capacities of the T-shaped, end-to-face, mortise-and-tenon joints in pine plywood and oriented strandboard (OSB), and to develop mechanical models to predict its tensile, moment, and torsional resistance capacities.;Results of the study indicated that the tensile resistance of a stapled-and-glued mortise-and-tenon joint in pine plywood and OSB ranges from 505 to 1933 lb. and 306 to 845 lb., respectively; the moment resistance ranges from 780 to 4428 lb.-in. and 612 to 2309 lb.-in., respectively; and the torsional resistance ranges from 598 to 2292 lb.-in. and 439 to 1260 lb.-in., respectively.;The mechanical models proposed in this study were experimentally validated. The tensile, moment, and torsional resistances of a T-shaped, end-to-face, stapled-and-glued, mortise-and-tenon joints can be estimated based on knowing basic material properties of single-staple tensile, lateral shear resistance, and material end-to-face glue bonding tensile strength and shear strength.
