| Abstract |
This study evaluates the flexural performance of glued-in rod connections in structural beams made of glued laminated timber or glulam.
These joints provide aesthetic benefits and potential structural efficiency in mass timber construction, yet their flexural behavior remains
insufficiently understood. To address this gap, experiments were conducted with varying parameters, including glulam beam cross-sections, the
number of embedded steel rods, and beam spans. Some specimens were also reinforced with self-tapping screws (STS) to improve resistance
to delamination. Results showed that increasing the number of steel rods generally improved strength and stiffness, although large-section
beams experienced premature cracking between lamina layers that limited performance gains. STS reinforcement effectively prevented
delamination and enhanced overall structural performance. Experimental findings were compared with existing analytical models, offering
insights for refining current design methods. |
