This study presents mechanical properties of glued laminated timber members and performance of beam-column connections using Japanese cedar. As structural connections play a critical role in determining the overall stability and load transfer efficiency of timber frameworks, particular emphasis was placed on assessing both shear and tensile behaviors of connection systems. Full-scale tests were carried out to evaluate the load-bearing capacities of the connections under controlled laboratory conditions. The measured shear and tensile strengths were then compared to the nominal values provided by the manufacturer to verify compliance with design expectations. Results indicated that both connection types exhibited mechanical properties exceeding the prescribed limits, thereby confirming their structural reliability. These findings contribute to the body of knowledge supporting the application of engineered timber in modern construction and demonstrate the viability of Glued Laminated Timber systems for safe and efficient structural use in building environments, particularly in regions considering broader adoption of sustainable timber technologies.
