Moments (Ultimate)
This section gives the magnitude and location of the design moments with the associated capacities.
| Setting | Description |
|---|---|
| Span | This indicates the span for which the values are being listed. It includes Left for left cantilever, Right for right cantilever, and Span for main span. |
| Cond | This indicates the load condition. It includes: |
| PreCmp+ | Construction Dead Load and Construction Live Load positive moment (top flange in compression). Values reported are from the support of cantilevers and at the maximum positive moment location for the mid-span of the beam (listed for composite beams only). |
| PreCmp- | Construction Dead Load and Construction Live Load negative moment (bottom flange in compression). Values reported are from the support of cantilevers and at the maximum negative moment location for the mid-span of the beam (listed for composite beams only). |
| Init DL | Initial, or Construction Dead Load (listed for composite beams only) |
| Max + | Maximum Positive Moment |
| Max - | Maximum Negative Moment |
| LoadCombo | This is the controlling Load Combination for the span and condition indicated. |
| Mu | This is the ultimate moment for the indicated Span, Condition and Load Combination. |
| @ | 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 unbraced length was not considered, as for a simple span composite beam, Lb is indicated with "---". Otherwise, 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. |
| Cb | This is the Bending Coefficient. If the unbraced length is zero, Cb is indicated with "---". |
| Phi | This is the Resistance Factor for AISC 360 LRFD and LRFD 3rd editions. |
| Ω | This is the Omega factor for AISC 360 ASD. |
| Phi*Mn | This is the design strength of the beam segment for AISC 360 LRFD and LRFD 3rd. |
| Mn / Ω | This is the design strength of the beam segment for AISC 360 ASD. |
| Controlling | This is the controlling set of values. |
