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.
