Özet:Flat plate systems are constructed with slabs directly supported on columns. Since there are no beams in the system, the behavior of connections between the slabs and columns play a crucial role. Due to the sudden and brittle nature of punching shear failures, slab-column connection design must be conducted with proper safety precautions. The first part of this study aims to evaluate the safety level of different design expressions in the codes. Fir this purpose, the ability of ACI 318-11, TS-500 and Eurocode-2 to estimate punching shear strength was examined in light of experimental results compiled from previous research. Interior and exterior connections were examined in the course of the study. In the second part of the study, beam and shell models were calibrated to simulate the load-deformation response of interior slab-column connections in light of experimental results. In the final part of this thesis, a typical floor plan of a flat plate system was analyzed to investigate the possibility of a progressivefailure mechanism after punching failure takes place at a slab-column connection. Minimum post-punching capacity required to avoid progressive punching failure in a floor was estimated. It is believed that, the results of this study can be helpful in guiding engineers in understanding the safety inherent in punching shear design expressions and to take necessary precautions against progressive collapse.
