Abstract
Research and development work (R&D), the main task of which was to assess the punching strength of flat floor slabs of monolithic reinforced concrete in the areas of support on the ends of the walls, was carried out at NIIZHB named after A. A. Gvozdev. As part of the study, experimental, as well as computational and theoretical studies were carried out on the issue of determining the strength of fragments of flat slabs for punching in the zones of the ends of the walls. On the basis of the research results obtained and their analysis, it was found that there is an influence of bending moments in the plane of the walls on the punching strength of the plate, which requires appropriate consideration in the calculation methods.
