Comparative Evaluation of Punching Shear Resistance of Flat Slabs Using Experimental Results and the Second Generation of Eurocode 2 with Nonlinear Analysis

Abstract:

The aim of this article is to compare the punching shear resistance of flat slabs without shear reinforcement, obtained from experiments, with the results of nonlinear analysis and the second generation of Eurocode 2. The experiments were conducted at the Slovak University of Technology over the past few years. The article deals with five axisymmetric full-scale flat slabs with dimensions of 2.50 × 2.50 m, each with a varying reinforcement ratio. The tested specimens had thicknesses ranging from 180 to 250 mm and were supported by square or circular columns with side lengths or diameters ranging from 200 to 300 mm.Subsequently, a nonlinear analysis of these specimens was carried out using the ATENA software. The results from the experiments and the nonlinear finite element analysis (NLFEA) were then compared with the predicted punching shear capacities according to the second generation of EC2. The punching shear resistances obtained from the tests show good agreement with the predictions by the EC2 (2023) and NLFEA when the CoV of the ratio V_R,exp/V_R,model reached a value of 0.05 in the case of NLFEA and 0.057 with the EC2 (2023) model. However, the results from the nonlinear analysis indicate differences in the deformation of the slabs at the failure load.
