For the calculation of the moment capacity, the unbraced length of the compression flange in the plane of the minor-axis of a beam is determined as follows: |
Except as explained below, the unbraced length is determined the same as is described in Section Compression Flange Bracing in RAM Steel Beam Design, including the effect that the Consider Point of Inflection option has.
When determining the moment capacity associated with a moment at a given point, if the flange that is in compression at that point is braced based on the Top Flange Continuously Braced or Bottom Flange Continuously Braced criteria or assignment, the unbraced length is set to 0.0.
