Progressive collapse of structures caused by extreme or accidental loads may lead to significant loss of life and property. Considerable research efforts have been made to date to mitigate the probability of progressive collapse and its consequences. This study summarises the fundamentals of progressive collapse in relation to the existing theoretical concepts and understanding. Specifically the existing theories pertinent to progressive collapse of building structures, in particular reinforced concrete (RC) flat plates, are examined from the following four key aspects: (1) definition of progressive collapse from deformation and/or strength perspectives with respect to the failure criteria of structural members and the entire structural system; (2) failure mechanisms of load-bearing systems undergoing progressive collapse with respect to the structural ultimate capacity, which has not been considered in the design process; (3) research methodologies for investigating collapse mechanisms, with emphases on experimental and numerical approaches; and (4) collapse-resistant design principles as covered in several international design standards in which a number of robustness requirements have been recognised. Based on the schematic review of the current trends and developments, gaps and limitations in progressive collapse research are identified and a new research direction is established to advance the progressive collapse study of RC flat plate structures.

“…Experimental testing was later followed by McPeake 17 and by Georgopoulos, 18 who proposed a design method accounting for the reinforcement and concrete strengths. Mitchell and Cook 19 investigated the role of flexural reinforcement on the post-punching strength. An extensive experimental campaign was carried out by Melo 6 and Melo and Regan 12 accounting for the role of the anchorage of the flexural reinforcement.…”

“…The method assumed that the membrane takes a circular deformed shape and that no tensile forces can be developed by the concrete. Cook [7] developed a geometric and material nonlinear model to predict the membrane response of RC slabs. Mitchell and Cook [7] discussed three methods of predicting the tensile response of slab panels having fully restrained edges and compared their models to test data in Park [5] and Brotchie and Holly [8].…”

Mitchell and Cook [7] discussed three methods of predicting the tensile response of slab panels having fully restrained edges and compared their models to test data in Park [5] and Brotchie and Holly [8]. Park and Gamble [9] concluded that steel reinforcement enables a damaged slab to 'hang' from its supports and that this may be the key for preventing progressive collapse of reinforced concrete slab structures.…”
