Moments

This section gives the magnitude and location of the maximum positive and negative moments with the associated stresses.

SettingDescription
Span This indicates the span for which the values are being listed, which is always listed as Center since cantilevers are not allowed for C-Beamâ„¢.
Cond This indicates the load condition. It includes:
SettingDescription
Precmp Precomposite load (Construction Dead Load plus Construction Live Load; listed for composite beams only)
InitDL Construction Dead Load (listed for composite beams only)
Max + Maximum Positive Moment
Max - Maximum Negative Moment
Moment This is the moment for the indicated Condition.
@ This is the location of the indicated moment, measured from the left end of the beam.
Lb This is the unbraced length for the segment containing the indicated moment. If the compression flange is fully braced throughout the segment, Lb is indicated with "0.0", meaning there is no unbraced length to be considered. Listed for noncomposite beams only.
Cb This is the Bending Coefficient. Listed for noncomposite beams only.
fb This is the actual bending stress in the beam for the moment indicated. Values for the Tension Flange and Compression Flange are included. Listed for noncomposite beams only.
Fb This is the allowable bending stress for the segment. Values for the Tension Flange and Compression Flange are included. Listed for noncomposite beams only.
Controlling This is the controlling set of values. Listed for noncomposite beams only.
fc This is the compressive stress in the concrete. Listed for composite beams only.
Fc This is the allowable compressive stress in the concrete. Listed for composite beams only.
