The article gives a description of the developed design of a sample of the connection of wooden elements, which is devoid of the shortcomings of existing technical solutions that allow simulating the actual operation of real wooden structures. The design makes it possible to increase the reliability of the test results, simplifies the test procedure and the test results processing process. The developed design of the sample fully reflects the actual work of the real joints of the beam cage of a wooden building, causes a stress-strain state in the sample, to a large extent similar to the stress-strain state of a real joint due to the correct application of the basic provisions of the similarity theory to connect the model with the full-scale construction of a wooden buildings, schemes for applying the load to the sample and methods for conducting experiments.

Keywords: wooden structures, timber, joining of wooden elements, testing of a sample of connecting wooden elements, wooden beam, main beam, secondary beam, metal plates, screws, reliability improvement
