On opening a Diamonds-beam in ConCrete Plus, you get the message:
ConCrete only supports the calculation of beams loaded in the plane (thus loaded with My and Vz). Consequently, ConCrete Plus only supports drawing the reinforcements plans based on those internal forces (My leading to Ay and Vz leading to Awz).
While Diamonds supports the calculation of beams loaded in and out of the plane (thus loaded with My, Mz, Vz and Vy)… Thus, if you export a Diamonds beam, loaded with Mz and Vy to ConCrete Plus, Concrete Plus will not take the reinforcement comming from Mz and Vy into account. You need to do that yourself. That’s what the message is saying.
