This research investigates the collapse behaviour of flat slab structures with column capitals through experimental analysis. Two 1/3-scaled specimens were subjected to complete collapse by uniformly distributed loads simulated by eight separate piles of concrete cubes. Accidental scenarios involving a loss of vertical support at mid-span or penultimate column locations were examined. The experimental observations yield several key findings: Overall, this study underscores the importance of column capitals in mitigating progressive collapse in flat slab structures and provides valuable insights into their collapse behaviour under various loading conditions.
