I have a HSS28x28x5/8 column and I do not know how to create that section in STAAD. I currently have a full 2D model of the structure and all the loads/properties (was previously used for design), but now I need to analyze the column with a hand hole in the column section. As far as I know, this has to be done in a 3D model. I was trying to get away with doing it in 2D and making nodes at the top and bottom of the hand hole and inserting the properties at that section but the torsional constant reduced from 227 in^4 for the full section to 6.09 in^4 at the hand hole.
So basically I am asking, how do I insert my own steel sections and how can I properly model this column with the hand hole? Or is there an easier way to go about this? The structure works without the hand hole and I need to make sure that it still will be sufficient with the hand hole and same loadings.
