Criteria Bracing
Selecting the command will cause the Column Bracing Criteria dialog box to appear, with the current default settings shown.
The bracing of a column in a particular direction affects the analytical model that is created. Where a column is braced above or below the story being analyzed, it will be assigned a rotational and translational fixity at that level.
| Setting | Description |
|---|---|
| Bracing by Slab | An option is provided for the slab to automatically brace the column. If a column does not fall within a slab, at a particular level, this criterion will not brace the column at that level. |
| Bracing by Beams | Additionally, beams framing into columns may cause the columns to be braced. The maximum angle (0 - 90 degrees) for which a beam braces a column may be specified in the edit box provided. If the angle between a given column axis and the beam exceeds the value specified, the beam does not provide bracing to that column in the axis specified. |
To change the bracing criteria, click on the desired bracing options and/or enter a new maximum angle in the edit box. Clicking Cancel to cancel any changes made. To accept the changes, click OK.
