Effect of Stacking CFRP Sequence on Strength Resistance of Connections in Glulam Structures

About the Project

The future of sustainable construction is taking shape with engineered timber, and glued laminated timber (glulam) stands at the forefront. This versatile material is praised for its exceptional strength-to-weight ratio and ability to sequester carbon, making it an ideal solution for modern, eco-conscious architecture. Glulam's unique manufacturing process—bonding smaller timber pieces together—allows for the creation of long, complex, and curved spans that are unattainable with natural timber, making it a go-to for large-scale projects like auditoria and bridges.

While glulam's potential is vast, its connections remain the most critical point of vulnerability. Bolted connections are a common choice, but their mechanical performance in glulam structures can be a limiting factor. This PhD research will pioneer a novel approach to strengthening these crucial joints. The R&D project investigates how the stacking sequence of Carbon Fibre Reinforced Polymer (CFRP) can enhance the strength and durability of bolted glulam connections. Through a rigorous program of both physical experimental testing and advanced Finite Element Modelling (FEM), the study will provide crucial practical insights. The findings will not only advance our understanding of hybrid CFRP-Glulam connections but will also offer a new design paradigm, contributing to the development of safer and more efficient timber structures by optimising their stiffness, load-bearing capacity, and ductility.
