Lateral Load Bearing Strength of Wire Nails in Plywood-to-solid Wood Composite Joints for Partially Prefabricated Structures

Extensive laboratory tests have been conducted under six series of experiments to study the effects of two species of varying density from strength groups, thickness of constituent members, inclination of loading to the direction of grain of timber and face veneer orientation of plywood, preboring plywood, etc. Analysis of results done at different levels of derivations have revealed a definite trend in applications as to the preference of a particular plywood thickness, timber thickness and strength loss on preboring plywood but no generalized conclusion have been drawn. Bearing strength of wire nails presented for different types of joints may be safely used as designfunctions in plywood-to-wood composite structures.
