Abstract
The paper describes a universal test bench, designed to conduct full-scale studies of the strength and stiffness of joints of building structures. The paper present the results of full-scale tests of the joints of beam flanged connections with columns in the elastic and elastoplastic stage with the determination of the dependence of their yield on the value of static loads. The study was conducted on 12 models with both one-sided joining of the beam to the column, and with two-sided, for which the flange thickness, resistance class and the controlled tension of the bolts, loading scheme were varied. The experiments were carried out according to a multifactorial plan until the destruction of the models. According to test results, 4 characteristic trilinear diagrams were obtained for dependence of the angles of rotation versus bending moments. The obtained results can be used in the design of flange connections and during the verification of their design models.
