Resumo: | Among the existing construction systems, Glued Laminated Timber (GLT) stands out as a structural product. In this method, selected wood laminations are arranged so that their fibers are aligned parallel and are bonded using adhesives. Epoxy adhesive is a thermosetting polymer formulated from resin, which can be used for bonding various materials in civil construction. In this context, this research evaluated the shear strength of joints bonded with epoxy adhesive using Pine wood at different angles. The joints were created at angles of 0°, 10°, 20°, 30°, 45°, 60°, 70°, 80°, and 90°, and were subjected to shear tests under compression and torsion. Based on regression analysis, the Hankinson formula proved suitable for estimating shear strength under compression, returning a coefficient of determination of 0.89. However, for shear under torsion, the model was not effective, with a low R² value. The test specimens subjected to compression exhibited a distinct mechanical response compared to those subjected to torsion.
