| description | In multi-storey buildings that are asymmetrical in plan, an eccentricity occurs between the center of mass and the center of stiffness. Under the action of wind and seismic horizontal loads, torsion appears in the bearing system of the building. Torsion can also occur in nominally symmetrical buildings caused by uneven deformations of structural components. There are numerous analytical and experimental studies of the effect of torsion on bearing structures. It is required to assess the achievement of the ultimate states of reinforced concrete structures and shear bonds that create a spatial system. This paper uses computer simulation to study the stress-strain state of the welded bond under the action of shear and torque. Two joint models are considered, which are subject to only shear and shear with torsion. The results show the process of destruction of the joint, deformation of the shear walls to be joined, and a decrease in the rigidity of the connection. The study is useful for understanding the mechanisms of twisting effects during translational and rotational vibrations of a building. |
