every body,
i have a quesition , i am design concrete frame according to ACI318 , i found there are two module of calculation for concrete design:
staad analysis output of concrete design & concrete design in interactive design. but the same section designed have some different output
for exampe column section:500x700 , is ok in output of staad .but it is fail in interactive concrete design because of ",The column fails the Bresler criterion"
see attachment below:
Did not find any attachment with the post but in general I would go with the batch mode results ( analysis output ) when it comes to the US code. The interactive design mode does not have the latest versions of the code implemented and is not updated as often as the batch mode design is. For many international codes, interactive design is a prime design tool but at least for design as per the US codes, I would recommend using the batch mode.

Thank you very much for your play !
but i have another question , in interactive concrete design , there are some output of design, for example : unity ratio for column. but not same output in batch mode . the former have detail formula output of detail ,but just give us total reinforcement area for colum in batch mode , how to calculate unity ratio in the batch mode?
and i found there are more different reinforcement area between batch mode and interactive design for column reinforcement
how to explain ? can you help me ? thank u !
hi,
i have error msg
"The column fails the Bresler criterion"..
once i give design in interactive design , then all columns pass.
but again if i give design in interactive design then i get above error msg..
can you help me in this issue..
i have attached model for your reference.../

thankyou for your time.../

RC Designer is a deprecated module. I would recommend you to upgrade to the most recent STAAD.Pro CE version 22.05.00.131 and perform the concrete design in the Advanced Concrete Design workflow (RCDC).
