Test procedures for dowel type connections in timber structures

The aim of this paper is to define the test procedures to be followed in dowel-type joints of timber structures, in order to identify their resistant behavior in real situations. A new methodology is developed according to the new European regulations guidelines on real-size specimens, reflecting the main parameters to take into account during the tests and the evolution of the stress-strain relationships. Factors such as wood crushing, dowel bending and rope effect have been taken into account. From the analysis of prototypes, specific fittings and several series of tests on specimens have been prepared to develop the tests with three options. These are: joint with threaded bolt, joint with glued-in rod and joint with washers and nuts, all this with the objective of analyzing the behavior of the different types of connection.
