In the Firenwood project four different test series were performed to investigate the behaviour of glued-in metallic fasteners under the influence of heat, in particular for a fire load. In test series 3 two different test setups were used. The aim of this series was to link the me-chanical behavior of the joint with glued in rods to different temperatures. Therefore, test specimens with threaded rods were glued in parallel to grain direction in wooden specimens. At first, reference tests at ambient temperature were carried out. Specimens were loaded me-chanically under tension until failure. With these tests it was possible to derive the corre-sponding load levels for the tests with thermal load. The second test setup included thermal tests. Here the specimens were loaded mechanically to a constant tensile load based on the reference tests. Meanwhile they were heated to a tem-perature of 110 °C. This test setup is intended to examine the critical adhesive temperature and the influence of various test configurations on the failure behavior.     «
