Experimental performance of mortice and tenon joint strengthened with glass fibre reinforced polymer under tensile load

This paper reported on the experimental performance of mortise and tenon joint for beam-to-column structural member made of Kempas species. The joints were dowelled with glass fibre reinforced polymer (GFRP) and compared to the joints strengthened with steel dowel and wood dowel. The failure modes performance analyses were observed based on European Yield Model (EYM) theory according to National Design Specification (NDS) 2008. Results show that the experimental performance of the mortise and tenon joints dowelled with GFRP under tensile load may provide comparable strength to the joints dowelled with steel. The sequence of having the higher capacity to hold the mortise and tenon joints is by strengthening it using GFRP, followed by steel and wood dowel. The failure behavior of both joints dowelled with steel or GFRP were almost similar. Nevertheless, different behavior was shown in wood dowelled joints, the flexibility of wood dowels extended the displacement longer made the yield load and load at rapture extended compared to the other types of joints.
