Abstract Modern construction projects such as high-rise buildings require increasingly lighter and stronger wood frame shear walls. The stress level of the edge zone in the sheathing panel is generally larger than that of the middle zone under lateral loading, and the mechanical properties of wood-based panels are positively related with density. A series of fast-growing poplar plywood with a marginal or overall densification were prepared in this study for use as wood shear wall sheathing panels. The plywood density was controlled to 550, 550 (edge, 650), 550 (edge, 840), and 650 kgm−3, then full-scaled walls sheathed with the samples were monotonically loaded and compared against a wall sheathed with 12 mm OSB to determine the effects of densification. The elastic lateral stiffness of the densified plywood sheathing wall with marginal density of 650 and 840 kgm−3, relative to 550 kgm−3, increased by 39.8% and 47.8% as the ultimate bearing capacity was increased by 15.5% and 37%, which is better than the commonly-used OSB sheathing wall accompanied by slightly lower ductility. The lateral behavior of the plywood sheathing wall appears to increase as density increases. The marginal-densified plywood can substitute for overall densified material as it presents nearly identical lateral behavior when used as a wood shear wall sheathing panel. The wall with marginal density of 840 kgm−3 showed the best overall lateral performance in this experiment. Relative error was controlled within 10% using the rheological model proposed by Casagrande to theoretically verify the lateral bearing capacity and lateral displacement of the test wall.
Highlights The lateral resistance of the densified plywood wall is equivalent to that of the OSB wall. The performance of the edge-reinforced plywood wall is same as the overall-reinforced. The lateral behavior of plywood wall is positively related to the plywood density. The wall sheathed with 840 kg⋅m-- 3 plywood has the best lateral performance.
