How to show fully braced beam for AISC beam design

[bjur]

Attached is a simple frame where I wanted to verify the different unbraced settings in Robot and their effect on the moment capacity.  I can't seam to get the beam to show the moment capacity for a fully braced beam.  Attached are hand calcs vs the results that Robot gives me.  I can't seam to get the unbraced length for the beam to show up as 0ft.

Thank you again.  However I think this was a bad example on my part.  Attached is a better example showing the same beam W18x50 under simple loading.  If I set the bracing for the top of the beam to the "X" (which is displayed as None), the beam is calculated for an unbraced length of 10ft.  I was under the impression that the "X" means it's fully braced.  If I set the unbraced length to 0ft manually as shown in the second picture, I get the expected results.  Why does the "X" result in different values than manually setting the top flange bracing to 0ft?  I might be missunderstanding the meaning of the "X"

Indeed X should work as 0ft. I have asked the development team to investigate this situation. Thank you for informing us about this issue.

The results for Robot 2015 SP3 for both settings are the same.
