If the width of the flange at stat node can de different with the width of the flange at end node ?
Current only width of top and bottom flange can de defined seperately.
As of now there is no way to do that. You may split the beam into segments and specify a different flange width for each segment. Each segment would have a constant flange width but at least you would be able to capture the variation of flange widths across the segments.
