Good day,
I have used Staad to model a composite slab and design the beams supporting this slab. However, upon completing the steel design in staad the design results presented are very strange. All the members passed, however the results only presented the ratio and the status (PASS) for most of the members, but it did not present the critical load combination, the critical case nor the specific clause that was checked in the AISC code. I have included a snippet of the results as well as the Staad file as a reference for the issue. In the snippet you will notice member 56 has all the expected results but members 54,55,57,58,59,60,61 do not have the same results.
