TO TEST VERTICAL WELDED BUTT JOINTS OF PANEL BUILDINGS

Abstract

In this work, an experimental study of the welded concreted joint on the shear force was carried out. The test was carried out only for shear, since the main static purpose of vertical butt joints of panels is to ensure the perception of shear forces arising in the joints when the mating walls work together. The object of the study was a fragment of wall vertical connection 125 a series of large-panel residential buildings, the thickness of which was 160 mm and the total height is 550mm. In result of experimental research defined stress-strain state of vertical butt joints and proposed approximating the dependence of the deformation of the weld joint from shear forces. The test results can be used in the calculation of load-bearing systems of largt-panel buildings taking into account the nonlinear compliance of welded joints.
