I'm using RAMSS (v15.04) to design the backspan of a small extension type cantilever (see snip) with the "use inflection point" and "perpendicular deck bracing the top flange" settings turned on. The backspan beam is being designed as a composite beam as the cantilever is not too significant. The pre-composite stage checks seem to use the expected unbraced length upto the inflection point. However, the critical "1.4DL" combo for the composite stage seems to be using the full 30' length of the backspan as the unbraced length instead of the expected length upto the inflection point for that combo. Any reason why the program is treating the unbraced lengths under different combos differently?
