Glued-in CFRP and GFRP rods in block laminated timber subjected to monotonic and cyclic loading

Current advances in timber engineering with the use of at longer spans necessitate high performance joints. Glued-in rods exhibit axial load capacity and stiffness are suitable for such applications. FRP can increase their durability fire but ways to produce progressive failure mechanisms necessary enhance resilience. In this study CFRP GFRP glued block laminated epoxy investigated under both monotonic cyclic loading. Joints constant glue-line thickness variable bond-line geometry studied induce resin mechanisms. A stepped wedge shaped varying a mirrored version were investigated. The effect elastic modulus (CFRP vs GFRP) on bond strength, material viscous damping explored. 11% higher loading serviceability stage. does not discount results due viscoelastic creep deformation. An withdrawal damping. Specimens superior mechanical performance. FEA model is presented numerical agree well experimental findings.
