Investigation on bending moment resistance of L- shaped screwed corner joints constructed of Plywood members

The goal of this study was to investigate bending moment resistance of L-shaped screwed corner joints constructed of Plywood members. The thickness of plywood members was nominal 19mm that were compared with medium density fiberboard (MDF) and particleboard with 18mm thicknesses. Effects of thread s...
