Hello first of all; I have a steel roof project, I am trying to find the most economical sections. I got a pmm error in the middle columns in my project. When I clicked on the column details, you saw that the moments in the minor direction were excessive. In the major direction, there is almost no moment. I also turned the direction of my columns, this time the pl20 column on the side was forced. 1- Is there a way to solve without enlarging the section? 2-Are the sections I used normal for a project of this size? 3- Could the issue I mentioned above be caused by modelling?
