This window is displayed when you create a new analysis or open an existing analysis. It is displayed as a floating window separate from the main application window. Closing this window will not close the analysis itself and will not lose any information about the analysis. To redisplay this window (when an analysis is open), select Analysis Inputs from the View menu, or press F4.
This tab contains general inputs and information for the analysis. See also Members Tab, Supports Tab, Loadings Tab, Combinations Tab, and Notes Tab.
| Description | Text describing the type of analysis. |
| Project | Text describing the use for the analysis. |
| Revised | The date and time of the last revision to the analysis inputs, and the name of the user that made the last revision. The user name comes from the Heading tab of the Options window. |
| Member Orientation | Choose between Horizontal for beams and Vertical for columns. This only affects how the members are displayed. This has no impact on other inputs. For columns, the locations are measured from the top down. |
Two member check options are defined on this tab:
| Calculate global buckling using elastic theory | Most of the global buckling equations in the AISI Specification are based on elastic theory. But special cases exist for unequal unbraced lengths and non-symmetric sections, where more rigorous elastic theory could predict a higher buckling stress. Choosing this option enables these advanced elastic theory calculations. For AISI Specification editions prior to 2016, using elastic theory may in some cases be treated as a rational analysis with more conservative safety and resistance factors. |
| Include torsion in member checks | If checked, the applied torsion bimoment is determined at each member check location, and the impact on flexural strength is included in the member check. |
