Resistance of Vertical Joints During Torsion of Multistorey Buildings
Floor slabs, vertical and horizontal joints determine the spatial interaction of the entire load-bearing system of panel, frame-panel buildings. Under the action of wind loads and earthquake loads, torsion of the bearing system may occur for a number of reasons. In the asymmetry of the load-bearing system in the plan building rotates around the center of stiffness. The assessment of torsion conditions in building codes based on the parameters of elastic systems with an asymmetric plan has been the subject of numerous studies in the past. Vertical butt joints of panels, referred to as shear connections, in this case are affected in two planes. In this work, a numerical study of the welded joint on vertical shear force and horizontal torsional action is carried out. The object of the study was a fragment of a vertical wall of large-panel residential buildings, the thickness of which was 180 mm, and the total height was 700 mm. The stress–strain state of the vertical butt joint is determined, data on the asymmetric deformation of the considered welded joint are obtained. The test results can be taken into account when designing load-bearing systems of large-panel buildings, taking into account the proposed algorithm for nonlinear stiffness of welded joints.
