The possibility of the occurrence of a second punching shear failure and of a Progressive Collapse after a punching shear failure had occurred in one flat slab column connection is investigated in two building structures, using Eberick and SAP2000 softwares and the Yield Line Method, and codes ACI318:2019, EUROCODE2:2004 and NBR6118:2014. It is shown that slab column connections should be designed and detailed to prevent Progressive Collapse and that Integrity Reinforcement should always be present, and that the remaining capacity of floors after punching failures depends on the i) post-punching resistance of the connection being punched; ii) post-punching resistance of the neighbors’ connections; iii) flexural resistance of the slabs, and that the flexural resistance of the slab’s floors can be evaluated by the Yield Line Method.

“…However, assessing structural robustness has also been carried out by analysing actual cases of collapse in a wide range of different types of structures [13,[19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. In all these studies, collapses were found to be due to several causes, e.g., improper design, underestimated design loads, unexpected extreme loads, improper manufacturing, or poor workmanship.…”

“…The popularity of slab-column structures and the complexity of the punching shear issue make this topic a research subject of many investigations [5][6][7][8][9][10]. The improper design of the slab-column structures may collapse due to the phenomenon of punching [11,12]. Many parameters influence punching shear resistance, e.g., type and strength of concrete [13][14][15], support shape and dimension [16][17][18], quantity and distribution of longitudinal and transverse reinforcement [19][20][21][22][23], membrane effect [24,25], the effect of the hole near to support [26,27], cyclic load [28,29], type of concrete [9,30], shear slenderness [31].…”

The proposition of a method to verify the punching resistance for very large supports based on the EN 1992-1-1 standard is described in this paper. The present standard guidelines for the calculation of the punching resistance for large supports are also summarised. The proposed direct method is compared with other standard methods using an example taken from design practice. This method consists of a direct check of the shear forces at specific locations of the control perimeter with the permissible shear force calculated from the EC2 standard. The method showed very good agreement with the experiment while remaining practical for applications. The method presented takes into account the actual distribution of shear forces in the vicinity of the support, taking into account the influence of non-uniform loads, irregular floor geometry, the concentration of internal forces at the corners of the support and the influence of the stiffness of the head used. The paper provides scientists, engineers, and designers new method (called the direct method) for estimation of the punching load-bearing capacity outside the shear cap.
