Iam trying to design Concrete beams for STAAD File in RCDC, but it gives me a Beam Deatiling Failure, I tried to change the size of the beam and the material used for the design but no matter what size i choose, this failure won't be solved . I have also ran an analysis in staad pro before putting it in rcdc and there were no errorsI hope someone could help me with this. Thanks!
Can you please attach RCDC file?

Hello,
I can see you have used ACI code and ductile design. As per this code, the column should be at least 20 times the largest longitudinal reinforcement in beam. This clause has been implemented in beam design and we have restricted the beam max longitudinal dia with respect to column dia. As in your case. column size is 300x300 and you opted for minimum 16 number bar, the program is uanble to find a solution.
So, instead of increasing the size of beams you should increase the size of columns so that this criteria fulfills. I think 400x400mm column size will solve the issue.
A similar issue has been discussed in the below link.
