ABSTRACT: In this study, the change in shear strength on radial and tangential surfaces of Calabrian Pine (Pinus brutia. Ten.) wood having different roughness
Mechanical properties of wood play an important role when used for different Compression or shear strength of a wood beam or truss used extensively for
The strength of wood increases as its density increases. The shearing strength of wood is 10-15% of its tensile strength in the direction of the grain. Shearing

Both lateral (single and double shear) and withdrawal capacities can be determined. Wood-to-wood, wood-to-concrete, and wood-to-steel connections are
Wood strength, including the relationship between grain direction and strength, specific gravity as an indication of wood strength, and additional ways to
