At the present time, light steel thin-walled structures are widely used in the world practice. Due to the availability of production, application of high-strength steel and aluminum alloys, installation speed and reduction of construction costs, starting from the zero cycle, such structures can be used both for low-rise and production facilities, in particular for transport infrastructure facilities (overpasses, bridges, service and technological facilities, etc.). However, the connections of elements of the thin-walled structures’ elements require more in-depth study. This paper presents some studies on the effectiveness of thin-walled structures due to the use of tongue and groove joints of metal profiles. This type of connection presupposes the use of special fasteners, which provide a receiving recession on one side of the overlapping sheet elements. On the opposite side, the fastener has a thickening, through which the tension of the bolt is made by punching the connecting metal. The bearing capacity of dowel-bolt connections is determined by the inclusion of an additional factor in the work of the connection (bearing stress—shear key), which does not participate in the work of conventional bolt junctions. Model experiments carried out with the Ansys Ls-Dyna PC have shown that the keyed-bolt junction is a promising method for increasing the reliability of steel structures in general due to an increased safety margin and deformability.
