【 摘 要 】

When designing large-panel buildings, it is necessary to take into account the work of wall panel joints. In addition to welded joints, monolithic joints in the form of pinned joints of the loop releases of adjacent wall panels are widely used. The main characteristics of a joint in the design scheme are its rigidity and bearing capacity under the action of shear and tensile (compressive) forces. This paper studies a new type of an inter-panel joint in the form of a fastener junction of wall panels made using a bracket of reinforcing steel and a metal plate joining the ends of the bracket. Due to the creation of a closed loop of voltages in the node, its high load-bearing capacity is assumed as well as the possibility of using this connection under dynamic effects on the building. An experimental study of the strength and rigidity of the joint at tensile loading along the joint axis was carried out, the breakdown of the joint, the stiffness characteristics and the bearing capacity of the samples were determined. The numerical modeling of the joint's work on stretching to the formation of cracks is carried out.
