Results of conducted cyclic double lap-shear adhesive timber joints tests were compared with available experimental re-sults on timber connections with standard mechanical dowel-type fasteners and with results of numerical finite element analysis. The study found that the shear strength, elastic stiffness and strength degradation capacity of the flexible adhesive connections were significantly higher compared to mechanical fasteners commonly used in seismic-resistant timber connections. The latter, however, manifested larger ultimate displacements but also yielded at lower displacements.Elsevier20212023-01-25 11:22:45Neznano16134UDK: 624ISSN pri članku: 1873-7323DOI: 10.1016/j.engstruct.2021.113125COBISS_ID: 82409219sl© 2021 The Authors.
