Input Design Parameters
These parameters were calculated based on the geometry of the model.
| Setting | Description |
|---|---|
| Lu: | These are the unbraced lengths with respect to the X‑ and Y‑axes used in design. |
| K: | These are the effective length factors. K will be 1.0 for a column braced at both ends; it will be 2.0 for a "flag pole" column (unbraced at the top of the column). |
| Braced Against Joist Translation: | The RAM Steel Column Design module assumes that all gravity columns are braced against joint translation. |
| Column Eccentricity: | These are the eccentricities of the beam‑column connections. They are based on the user‑specified criteria, and are used to calculate the unbalanced moment. |
