Abstract
The strength and compliance of the joints of load-bearing structures in multistorey panel buildings is determined by different parameters and significantly affects the forces and stresses that occur in the elements of such structural system. Horizontal action on a structural system consisting of prefabricated wall panels, under certain conditions, can lead to a situation where torsional mode will prevail. The key conditions for the occurrence of torsion, which are noted in most studies on this topic, will be the horizontal and vertical asymmetry of the building and significant horizontal loads. In this experimental work, fragments of wall joints were tested under the action of shear and torsional loads. The fragments of reinforced concrete panels were joined using a metal butt joint during welding. A metal plate acted as a connecting element. According to the results of the experiment, the stress-strain state of full-scale fragments of panel buildings was obtained. The nature of the destruction, maximum shear and torsional loads have been established. Joint deformation diagrams are constructed for all test samples.
