Hi;
Just from doing the loadtakedown on column in RSA, and why do RSA doesn't take into account the floating columns and many others columns during the load takedown?. Even for the corner columns, the moment(M) is not taken into accounts. I'm i right or there's a workaround to get this result. Need a hand in this 🙏.
Hi @Djokaboris
The huge displacement is caused by no supports on the elevator. Just from inserting it Sir.
You can’t add supports at elevators, because you’ll change structure behavior. You may use some Kz percentage for Kx ad Kx to simulate raft-soil friction.
For the beams and columns, i don't have problems with it because i can easily size and design it in the RC design GUI without errors.
This is not correct. Using dummy beams and columns will affect slabs and raft design. Raft punching, slabs reinforcement and deflection will not be correct.
For example warning about "Punching force is too big" is due to columns section or raft thickness or both
I recommend you to take some time to define your structure with real elements before trying to design.

Hi Sir @Simau
Many thanks for your answers and recommendation. Just from including the real size of beams and columns but Robot freezes when the calculation is run.
Hi @Djokaboris
The model works, but with remaining warnings about incoherences on edges (due to geometric inacurancies you have to fix)
You have also issues with raft punching at colomuns ompacts (Blue is ok, green you need to add punching reinforcement and red you must increase column section or raft thickness)

Hi Sir @Simau
Many thanks for the time spent on the file, but because of the errors displayed there's no FEM results.
how to solve the freezing problem, if i may ask?

Hi Sir @Stephane.kapetanovic
Thanks for your help and answers. Please is there a way of having this section in Robot RC beam design GUI ??
hi @Djokaboris
you've already asked the question here, I don't have the answer but you should try the fourth with a slab on one side only.
