I'm using the user-supplied subroutine USRCRV for this problem.
After all I didn't find (and don't think there is) a way to do this with the MULTLN function.
Well, i think that will be only option for an accurate Stress-strain relationship...
And you found suitable results with the user-supplied subroutine!?
It was too hard to develop that subroutine!? Because i'm running out of time, and i don't wanna spend too much time learning how to create that subroutine, tha could possibly not even work well!
I tried to use the other models as Thorenfeldt to represent the compressive behavior of the concrete under high temperatures as close as possible of the ones presented in EUROCODE 2.
I had the same problem with the Steel, but i think i managed to represent the stress-strain relationship present in Eurocode 3 with the plastic strains dependent to the temperature.
But i would be a lot more satisfied if i could use a multi-linear temperature dependent curve...
Just sharing my problems!
This could be a nice feature of a new release of DIANA.
Do you have an e-mail that we could talk about those problems, it would be a lot more easier! Mine is fabio.rocha@usp.br!
Thanks a lot!
I have the same question
I have the same question too!
Did you solve that problem!? Or you used another curve for the compression/tension behaviour?!
Thanks
