The paper presents the results of a comparative analysis between numerical calculations of T-stubs of the 3rd stage of FEM models hierarchical validation and the results of laboratory tests. The procedure for the development of the material characteristics used in numerical calculations of FEM models is presented. The scope of this article allows determining the non-linear characteristics of the T-stub which maps the work of the end-plate joint of the beam to the column in the tensile zone. The results of laboratory tests of a series of T-stubs made of rolled profiles (HEB240, HEA240) and of welded profiles (thickness of end-plate: tp = 12 mm and tp = 20 mm) have been presented. The principles of shaping the geometrical features of the FEM model of end-plate joints of the T-stub type are given, with particular emphasis on the shaping of the bolt with a thread. The impact of the bolt thread on the accuracy of the obtained results was assessed. The criterion of reliability of the obtained results with respect to the maximum force in the bolt obtained on the basis of laboratory tests in the axial tensile test of the bolts in the configuration: bolt - washer - nut was formulated.
