THE BEARING CAPACITY AND DEFORMABILITY OF WELDED VERTICAL JOINTS OF LARGE-PANEL BUILDINGS ON EMBEDDED PARTS

Analysis of the research results presented in the scientific and technical literature showed the absence of data about the operation of welded vertical joints of large-panel buildings on embedded parts with connecting elements in the form of bent and rolled angle bars. In order to determine the technical parameters necessary for the calculation and design of large-panel buildings, experimental researches of the operation of welded vertical joints on embedded parts with connecting elements in the form of bent and rolled corners under the action of tensile and shear forces were carried out. The static load was applied in stages until the destruction of the prototypes. During the experimental researches, the displacements in the place of bending of the connecting elements of the prototypes were recorded. On the basis of the experimental data obtained, the values of compliance of the connecting elements of the vertical joint on embedded parts were determined. Correction coefficients for the correct definition the compliance of connecting elements in the form of rolled and bent angle bars of a vertical joint on embedded parts are calculated and proposed. A different nature of deformation and destruction of welded vertical joints on embedded parts with connecting elements in the form of rolled and bent angle bars with the same geometric dimensions under the action of tensile and shear forces on the joints is revealed.
