Abstract

This study was performed to characterize and understand static loading capacities of the T-shaped, end-toace, 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-toace, 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-toace glue bonding tensile strength and shear strength.
