<p>In this paper, an experimental investigation was carried out on a total of two specimens representing interior slab-column connections of flat plate in order to verify the effects of torsional resistance of slab-column connections of flat plate under seismic force. The test parameter was the existence of slits in front and back critical sections in order to transfer moment only by torsion. Punching shear failure occurred in the benchmark specimen without slits whereas torsional failure occurred in the specimen with slits. Furthermore, the deformation shapes of the specimens were different. Based on the test results, an equation to calculate punching shear strength is proposed.</p>
