Is there any option to get report for the tension & compression flange stress ratio of built-up I-section for the critical load cases.
Assuming your question is related to STAAD.Pro, the design considers failure modes like yielding, local buckling etc. for the individual elements of the cross section and the utilization ratio is reported for the cross section as a whole based on the governing failure mode. There is no individual reporting of the utilization for each element of the cross section.
