I am designing a basement mat foundation and found a discrepancy between the bottom reinforcement that RAM recommends. There are significantly more bottom bars provided by the reinforcement layer (figure 1) than the design status layer (figure 2). However, when "design flexural sections" is turned off in the design strip punching checks plan (figure 3), the reinforcement and design status bottom rebar are the same. Is the flexural reinforcement from the punching checks plan later supplemented for by the mat rebar and not necessary when the design status recommendations are made? Should I go with the reinforcement prescribed by the reinforcement or design status layer?
Figure 1: Reinforcement Layer Bottom Bars
Figure 2: Design Status Bottom Reinforcement Plan
Figure 3: "Design Flexural Sections" turned off on Design Strip punching Checks Plan layer
Thank you Karl
You should use the reinforcement that is detailed on the Reinforcement Layer for your deisgn.
The reinforcement displayed on the Design Status Layer is reinforcement required at cross sections in design strips and does not include reinforcement required for the flexural section check. The later requirements are checked with the punching shear check and not the design strips.
Also, the boxes marked in the image below need to be checked to see details about the flexural section design on the Design Status Layer.
