Link Settings for General Footings |
|
When linking reactions to the active general footing calculation, there are three main components to this portion of the window:
1) Align Column +X to: Start by selecting how the column should be oriented relative to the General Footing. Since columns and footings use different local axis conventions, it’s important to define the column’s orientation accurately.
NOTE:
•Reactions are always applied equal and opposite from the upstream member. For example, if the upstream column calculation reports a +Vxx reaction, this will impose a -Vxx reaction on the footing.
•Additionally, by specifying how the column’s local +X axis aligns with the footing’s local +X axis, the program can correctly interpret the direction of all shears and moments as they relate to the footing.
•All required sign conversions are handled automatically and will account for differences in local axis conventions.
2) Info button: Click this button to view a graphic that illustrates how different column orientations and their reactions apply to the supporting footing.
By changing tabs at the top of the window, you can view the various options for column orientation. For convenience, you can also click Link Load with Displayed Orientation at the bottom of the window to apply the reactions using the current view.
3) Add the Linked Load: Once you've defined the orientation settings, click Link Load to add the linked reactions.
NOTE: The General Footing module supports only one linked load at a time. If the Link Load button is disabled, it usually means a linked load already exists. In that case, select the existing load from the Linked Reactions Table and remove it before adding a new one.
Once you've click the Link Load button, you will see that the new linked load has been added to the Linked Reactions Table.
