ConCrete Plus does not draw the lower reinforcement

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

1. Lowest line: these are reinforcement quantities for moment transfer, let’s call this M_reinf
2. Second line:  these are the reinforcement quantitis for shear force transfer to the supports, let’s call this V_reinf

When you are using

• discontinuous anchorage > fill out the V_reinf
• continuous anchorage > do not fill out V_reinf, BUT add this value to M_reinf when determining the reinforcement bars. So make sure you put M_reinf + V_reinf

If the lower reinforcement still isn’t drawn, you might reconsider the suspending settings.
