Assign - Link/Support Loads - Gravity

Form: NLLink Gravity Loads

This loading method is a way to add the factored self weight of the members as a force in any of the global directions. It is recommended that the actual self weight of the structure be included in the definition of the static load cases.

Select one or more Links to be assigned a load(s).
Click the Assign menu > Link/Support Loads > Gravity command to access the NLLink Gravity Loads form.

Load Case Name. Select the load case to which the gravity load is being added. Alternatively, click the + (plus symbol) beside the drop-down list to access the Define Loads form; use the form to define a load case that will then be available in the drop-down list.
Gravity Multipliers. Provide Gravity Multipliers in the specified global direction.
Coordinate System. Select the coordinate system for the link/support.
Option. Specify how the load is to be applied.

Add to Existing Loads: Adds the specified load to the selected link object. If one or more gravity load assignments have already been made, this option increases the load, assuming that a positive load is being specified.
Replace Existing Loads: Replaces the currently specified gravity load, if any, with the new load. If no assignment exists, a new assignment is made. This is the default option.
Delete Existing Loads: Deletes any and all gravity load assignments made to the selected link object. When this option is selected, the items in the Gravity Multipliers area of the form are ignored when the OK button is clicked.

The screen will refresh with a graphical representation of the load assigned on the members selected.
