| Title of the article | Theoretical investigations of the stress-strain state of flat reinforced concrete floors punching in places of interface with columns |
| Abstract. | Problem statement. The purpose of the study is to study the theoretical data of the previously proposed structural solutions of the junction of the overlap with the column, the development of methods for calculating the flat concrete floors for punching using models of operation and destruction of concrete and reinforced concrete. Results. The main results of the study consist in the analysis of scientific papers on the topic of the joint of reinforced concrete slab with a column, comparison of methods for calculating the slabs for punching in places mates with columns for Russian, Belarusian, European standards. Different approaches to the calculation give different results, which differ significantly. Conclusions. The significance of the results for the construction industry lies in the fact that the results of theoretical studies are applicable to create a technique that allows to perform calculations on the extrusion of flat concrete floors in the places of conjugation with columns using a frame-rod model. Flat floors contribute to the maximum use of space-planning solutions, including the height of the floor, facilitate wiring under the overlap of utilities. |
| Keywords. | frame-and-rod model, the calculation of the ceiling for punching, horizontal joint, local compression, the hypothesis of the wedge failure due to overcome the resistance of the concrete detachment, shear, and crushing. |
