【 摘 要 】

Flange connections are structural elements used for joining different members of metal structures, as they determine the rigidity and strength of the structures as a whole. The difficulty of estimating the stress-strain state in the elements of the flanged joints is associated with the following factors: the three-dimensional geometry of the mated parts; the contact interaction between the elements of a bolted joint at the stages of its assembling and operation; the need for mathematical modeling of deformation processes in the framework of the theory of inelasticity. In this paper, the results of experimental and theoretical studies on the deformation behavior of the elements of a metal beam-to-column flange connection are presented. Experiments were conducted on large-scale samples subjected to elastic and inelastic deformations required for complete failure of these samples. Displacements at the characteristic points of the samples were recorded during loading. Relative deformations were measured at the points of the greatest concentration of stresses and strains. Such a set of quantities measured on different scales most accurately characterizes the interrelation of the deformation processes in different elements of the sample, especially when the deformation becomes inelastic. Theoretical studies were concerned with the development of a mathematical model capable of providing an adequate description of the distribution of elastic and inelastic zones in the elements of a flange connection.
