Good Morning all,
I am working in ETABS on a new building design that involves some PT transfer beams. Beams have been designed separately but I'm including them in our gravity ETABS model to take into account the PT effect on deflection. This is the first time I've ever used PT in ETABS (or SAFE for that matter), typically we use concept for PT design. So based on a quick search it seems like it should be a pretty straight forward thing to model PT in beams, just model the beams as usual, draw the tendons, then the dialogue box for the tendon profile pops up, fill in the profile info (including # of strands) and that's it (is my assumption). But I'm getting some warnings that I can't find any info about online, screenshot of warning log attached. Is there an additional step? I can't imagine ETABS forces you to apply equivalent balance reactions at the supports... or something like that. The deflection plots actually look pretty in line with where it should be based on the PT effect so I feel like it's actually modeled at least close to intended.
Any help would be greatly appreciated
