| Popis: | The purpose of the study is to analyze previously developed structural solutions of the “slab-column” unit under various modes of static and cyclic loading using various reinforcing elements and types of concrete, to compare methods for calculating the slab for punching at the fillet places with columns according to Russian, Belarusian, and European standards. Calculations at different standards give different results, which differ significantly from each other. The main objective of the study was to develop a methodology for calculating flat reinforced concrete slabs for punching using a frame-rod model of work and models of destruction of reinforced concrete in a compressive power flow. The significance of the results obtained for the construction industry lies in the fact that the results of theoretical studies are applicable to create a methodology that allows calculating the fracture from overcoming the concrete resistance to tearing, shear and crushing when forcing flat reinforced concrete slabs at the fillet places with the columns. Flat slab contribute to the maximum use of floor height, provide an effective location below the slab of utilities. |
