THE COMPLIANCE OF VERTICAL JOINTS OF LARGE-PANEL BUILDINGS MADE ON EMBEDDED PARTS

Abstract

Based on the analysis of scientific and normative literature, modern types and design solutions of vertical joints of large-panel buildings are considered, their main advantages and disadvantages are given. The features of determining the compliance of vertical joints on embedded parts as a complex, multi-factorial dependence on the combination of flexibility of the structural elements of the joint, namely, the flexibility of embedded parts of mating wall panels, the flexibility of connecting elements and the flexibility of welded joints, are considered. Examples of determining the compliance of embedded parts of wall panels and the compliance of the connecting elements (patch plates) by analytical methods under the action of a shear force, with various designs of embedded parts are given. The results of experimental investigations of the compliance of welded joints on the embedded parts are presented and analyzed.
