when I use the Karamba3d to analysis the same structure, it appeared different results. when I rotate the model, the results of Karamba3d analysis will change, but in fact a structure internal force size won’t because of my initial structure change with the different placed (under the same load), Could you give me some possible reasons for this result?
Attached my model file and the results of my calculations.

Hi, your columns in the rotated version as not rotated and therefore the internal forces are slightly different
If you rotate the cross sections of the columns then you get the exact same results

Thank you for your answer, I understand the reason.
