In Profis, how does the program calculate edge breakout for shear when no. 4 bar or no. 4 bar with stirrups are selected?
How does the program calculate concrete edge breakout for shear when reinforcement shear condition A or B are selected?
What are the ACI 318 code references for this? Is there a sketch that conveys what rebar condition / configurations meet the program design intent?
Hi Carrie,
Information on how PROFIS Engineering evaluates concrete edge breakout in shear can be found in Section 2.1 of the PROFIS Engineering Design Guide, which includes references to ACI 318-19. Ψc,V will vary based on the selected supplementary reinforcement option, which is discussed in further detail on page 181 of the design guide. Also, information on the concrete strength reduction factor can be found on page 201.
