Description
Summary:This paper shows the test results for resin-glued steel rods under axial load. These steel rods are glued into timber using a two-component Hilti HIT-RE 500 resin. The timber species used in the tests was Tali. Three different anchorage lengths were combined with two rod diameters and two resin thicknesses. The test failure values have been compared to some available theoretical formulations. The formulation in the Eurocode 5 informative appendix is one of these. The results show a significant difference between the theoretical and the test strength values of these joints. This is mainly due to the fact that the theoretical formulations are based on tests on lower density softwoods. Therefore, the research demands more analytical-experimental work in order to achieve more precise theoretical models.
