The effects of moment transfer at the flat-slab-inner-column connection, and the influence of concrete strength on the punching resistance of slabs, are analysed in the paper. Seven full scale specimens are investigated experimentally and numerically. The results are presented as load-rotation curves and compared with the critical shear crack theory (CSCT) failure criterion, and with other comparable expressions. A detailed nonlinear FEM analysis, involving calibration of model with experimental data, is conducted to ensure better correspondence of numerically obtained load-rotation relationship with experimental results.
