Good afternoon,
I am designing a staircase and need to limit the deflection.
When calculating reinforcement Robot takes the wrong deflection into account and requires a lot of reinforcement in the inclined part and barely any at horizontal parts.
Is there a way to change which deflection is calculated as shown in the picture?
Could you zip and share yuou model

If you use the same reinforcement type for all stairs panels (for example Perdanga X) you'll get same deflection.

I may have been misunderstood. Here is the scheme of the issue I had in mind.
Inclined part of the staircase requires the same amount of reinforcement in both scenarios, but the flat
parts aren't the same, simply, because Robot doesn't have to increase rq. reinforcement area where deflection is lower than required.
Controlling deflections by lowering maximum allowed cracking width seems to be the solution to the problem. It's just
weird to me, that robot doesn't pickup the right deflection at the flat parts of the staircase. Maybe I am missing something.
I made some modifications to your model:
- New Reinf type
- Decrease of stairs thickness
- Pinned lineare releases
When Deflection verification is done, you get messsage that admissible deflections has been exceeded for all panels, but only inclined panel deflection is diplayed, not for horizontal panels.
