Abstract. pin (finger) joints of steel structures are often used in construction when it is necessary to create ideal hinge joints, as well as for aesthetic reasons. As an example, the support units of the inclined and vertical pillars of the operated canopy at the reconstructed object in Moscow are considered. When calculating and designing them, the authors solved a number of complex problems using numerical and experimental studies. The well-known destruction of the finger joint of the roof cable tie fastening in the Krylatskoye Ice Palace (Moscow), together with a large variation in the choice of strength calculation methods and the lack of recommendations for calculating operational suitability caused the need for multifactorial studies of the strength and deformability of pin joints. Joints are the most important part of the structure, and the destruction of any bearing system begins with them, therefore, the determination of their actual stress-strain state and the development of an optimal calculation method is an urgent task. The article presents the analysis and results of theoretical, numerical and experimental studies on the strength and deformability of pin joints used at the facility reconstructed. On the basis of the research carried out, recommendations for the calculation and design of pin (finger) joints of steel building structures are presented. These recommendations make it possible to guarantee the fulfillment of the regulatory requirements for building structures in terms of strength, serviceability and durability.
Key words: steel structures, finger joint, pin joint, hinge, strength, deformability, computer simulation, testing. - REFERENCES
