Abstract

The increase in the number of storeys is impossible without deviation from standard projects, where the structure of assemblies is not designed for buildings that have more than 12 storeys. That’s why it’s necessary to strengthen assemblies. For that purpose the testing of assemblies of the panel system, which is unique in modern textbooks on design, is performed. The paper presents the results of tests conducted at the plant ZHBI-Vostok of Chelyabinsk. The strength and stress-strain performance of an external horizontal assembly in two different versions (with slab-wall junction and without junction) is evaluated. As a result of experimental data processing, the effect of force eccentricity on the stress condition of assemblies is determined. This influence should be taken into consideration in case of hand calculations on assemblies. The axial and angular strain before the failure of assembly samples and the strength reserve of studied structures are specified
