Error Messages
The following error messages may appear during the design process.
| Setting | Description |
|---|---|
| N* > Nomx or N* > Nomy | Displayed when total axial load in the member exceeds the elastic critical buckling resistance for the member in the plane of bending. This has implications in the calculation of interaction values. |
| DelatSx Undef.., DelatSy Undef., DeltaSAxial Undef. | Displayed when P-Delta is selected to be considered in the analysis and total vertical load supported by story exceeds the story/diaphragm shear. This has implications in the calculation of interaction values. |
| DeltaBx > 1.4, DeltaBy > 1.4, DeltaSx > 1.4, DeltaSy > 1.4 | Displayed when the moment amplification factor exceeds the code specified limit 1.4. The engineer can choose to consider P-Delta in Analysis if δs exceeds the code limits. |
| T-O in Bend | Some tension-only members (flat bars, rods etc) do not have bending capacities calculated. This error is issued if one of these member types is subject to a bending force following an analysis. |
| T-O in Comp | Some tension-only members (flat bars, rods etc) do not have compression capacities calculated. This error is issued if one of these member types is subject to a compression force following an analysis. This should only occur if the user assigns a tension-only shape to a member that is then not designated to be tension-only. |
| A-O in Bend | Some members capable of withstanding both tension and compression forces only do not have bending capacities calculated. This error is issued if one of these member types is subject to a bending force following an analysis. |
