It gives A1, B2. How can I handle B2 irregularity

[inş_müh]

Friends, I put 5 30/25 columns on the lower beams in the attic, I couldn't understand if it was because A1, B2 gives irregularity. How can I deal with B2 irregularity. The project is attached. I would be glad if you could help. Thanks in advance

Re: Irregularity Hello, The connection of the columns that you have defined on the beam with the beams is incorrect. Right under the column you need to split the beam in half and create a node there. Check connections for deformations in the 3D frame model after analysis. It seems that there is no connection in your project where I show in the picture.
