This thesis investigates the mechanical behaviour and optimization of glued-in rod (GiR) glulam connections reinforced with birch plywood plates. Utilizing both Eurocode 5 standards and computational models in Abaqus CAE, the study provides a detailed comparison between experimental results and numerical simulations.
The glued-in rod connections, a modern method enhancing joint integrity in timber constructions, are evaluated under varied loading conditions to assess the effectiveness of plywood reinforcement. Experimental tests performed include varied rod diameters and plywood thicknesses, with special attention to joint splitting and shear force distribution.
Numerical simulations are conducted to replicate and verify experimental outcomes, focusing on the improvement of design parameters for GiR connections. Results indicate that plywood reinforcement substantially increases the structural capacity and load distribution efficiency of the connections. The study addresses the critical need for optimized design criteria in Eurocode 5, suggesting enhancements based on comprehensive numerical analysis and experimental validation. Recommendations for future research include detailed examination of adhesive properties and their impact on connection performance.
