Edgewise flexural properties and modulus of rigidity of different sizes of southern pine LVL and plywood
2001
Biblis, E.J.
The results of this study confirm that modulus of rupture (MOR) values of southern pine plywood and laminated veneer lumber members are influenced by the beam depth when tested at the same span-to-depth ratio. As the depth increased, the MOR values decreased significantly among the tested groups. Edgewise moduli of rigidity (G) values (average of 36 ksi) for different grades and constructions of plywood members were obtained by a method that requires flexure tests at different span-to-depth ratios. These values are less than one-half of reported average G values for southern pine plywood obtained by a rectangular plate shear method.
