Abstract

The modern use of through-thickness reinforcement in wood glulam (glued laminated)beams, bridging the potential delamination crack faces, has shown to be an effective technologicalsolution to improve their interlaminar fracture strength. In this paper, the behaviour of woodglulam beams is investigated from an experimental and numerical point of view, comparing themechanical response of unreinforced and reinforced (by FRP rods) beams subjected to four pointsbending tests. For the numerical analysis, a simple two-phases (joint and reinforcement) interfacemodel has been formulated and implemented in a finite element code. In particular, the classicalinterface model for adhesive joint, able to describe the debonding between adjacent laminae, hasbeen enriched to take into account the heterogeneity due to the transversal reinforcement.
