    Abstract. Due to stricter design requirements for joints of steel structures with a yield strength over 375 MPa, the effectiveness of the use of high-strength steels is significantly reduced. Experimental models of friction joints made of high-strength steels tested for compression and tension with bolts are considered. The test results are presented and analyzed. Based on the analysis of the data obtained, it was revealed that when designing multi-bolt friction joints with two friction planes, a decrease in the interbolt distance does not give a difference in the results both in bearing capacity and in the deformability of the joints. The influence of the eccentricity of force transmission through one-sided pads has been established. The influence of the size of the bolt head, nut and washer, as well as the method of processing and the roughness parameter of the contact surface on the bearing capacity of friction joints, were determined. According to the results of a comparison of theoretical calculations and experimental studies, it is recommended to use hardware with enlarged bolt heads, nuts and washers in friction joints. The actual work of friction-shear joints is analyzed, after the breakdown of the contact surfaces, it is recommended to consider the joint as a shear without taking into account the friction component.
