Summary: This research aims to compare the design of unbonded prestressed concrete flat slabs, subjected to punching shear in supports, with bending moment transfer in the connection. The analysis were performed using NBR 6118: 2014, EN 1992-1-1: 2004 and ACI 318-19, with a calculation routine done in Microsoft Excel. The Structural Analysis Programs (STRAP) software was also used, to obtain the connection stress, given the eccentricities of the models. The procedures were compared to each other, and an analysis was also made of the parameters used for design, such as: overload, column sections, prestressing concrete stress, flexural reinforcement rate and concrete compression stress. The models included columns with bending moment in one or two directions and edge and corner columns. In general, the normative procedures NBR 6118: 2014 and EN 1992-1-1 were more economical for punching shear design than the ACI 318-19 standard.
