I am creating a Built up profile in Staad select series 5. Profile size is 300 X 600mm . flange thickness 20mm.. web thickness 16mm.. But after creating, if i export it to UPT file and open profile in staad it is showing member with different properties.
More over if i create the same section with user table the stress ratios are different with same profile created using section wizard. Why is that?
Sec and upt file is attached.
