Question:
When designing a plate, I get different reinforcements in different load situations with the same bending stress. What can be the reason?
Answer:
For design on a 3D model, you should pay attention to axial forces. The axial force can affect the loading of the respective direction, but can also affect the minimum lever arm.
In RF‑CONCRETE Surfaces, the smaller lever arm from both reinforcement directions is applied in 3D structures. In this context, the axial force in Direction 1 can have an impact on the required reinforcement in Direction 2.
