Comparative analysis of the results of calculation of flat reinforced concrete slabs for punching
Incoming article date: 15.01.2022When designing flat reinforced concrete slabs, the most complex and responsible structural unit is the area where the slab is supported by the column. This is due to the action of large concentrated efforts and the greatest density of reinforcement. In view of this, the issue of choosing calculation methods that most accurately estimate the punching capacity for suchstructural units is relevant. The article analyzed experimental data for 73 samples of flat reinforced concrete slabs without shear reinforcement from 10 different sources and compared with the results of calculations of the punching shear resistance according to SP 63.13330.2018, EN 1992 Eurocode 2 and Model Code 2010.
