It can happen that you do not see any lower reinforcement, despite the fact you have defined enough reinforcement.
In the window for diameter determination, there are 2 lines in the lower reinforcement zone
- Lowest line: these are reinforcement quantities for moment transfer, let’s call this Mreinf
- Second line: these are the reinforcement quantitis for shear force transfer to the supports, let’s call this Vreinf
When you are using
- discontinuous anchorage > fill out the Vreinf
- continuous anchorage > do not fill out Vreinf, BUT add this value to Mreinf when determining the reinforcement bars. So make sure you put Mreinf + Vreinf
If the lower reinforcement still isn’t drawn, you might reconsider the suspending settings.
