    Abstract. Taking into account the wide spread in modern construction of multistory public buildings with steel frames designed as a braced structural system with hinge joints of bearing structural elements, the issue of studying the actual behavior of "girder-column" connections remains actual one. Numerous studies in this field prove that such connections are characterized by certain grades of stiffness which directly depends on their structural solution. Therefore, when determining the forces and displacements in calculations of frames of a braced framing, it is necessary to consider the layouts with joints which are able to perceive an appropriate portion of bending moments. To obtain a reliable picture of the stress-strain state of frame blocks at the elastic-plastic stage of work is possible on the basis of numerical calculation methods widely used when designing buildings. The article presents the results of the study of the stress-strain state and bearing capacity of a pliable girder-to-column connection at the elastic-plastic stage of work with the use of CAE ABAQUS on the example of the design of the pin joint with connecting elements in the form of paired vertical angles.
    Key words: steel frame; girder; column, pliable node, stiffness; rotation angle; support moment.
