Mechanical performance of timber connections made of thick flexible polyurethane adhesives

This study investigates timber connections with flexible polyurethane adhesives, which prove to have the potential for timber-adhesive composite structures without mechanical seismic regions. Results of conducted cyclic double lap-shear adhesive joints tests were compared available experimental results on standard dowel-type fasteners and numerical finite element analysis. The found that shear strength, elastic stiffness strength degradation capacity significantly higher commonly used in seismic-resistant connections. latter, however, manifested larger ultimate displacements but also yielded at lower displacements.
