M. To add a nodal load
To add forces or moments that act a nodes, use the following procedure.
Tip: Nodal
loads are also referred to as
Joint Loadsin the STAAD command reference.
-
Either:
- On the
Loading ribbon tab, select the
Load Items tool in the
Loading Specifications group
Tip: This will add the load item to the currently selected load group selected in the program status bar.
- In the Load & Definition dialog, select a primary load case in the Load Cases Details list and then click Add.
The Add New Load Items dialog opens. - On the
Loading ribbon tab, select the
Load Items tool in the
Loading Specifications group
- Select the Nodal Load > Node tab.
-
Type the force and moment magnitudes acting in the global
directions (with sign) applied at the same nodes.
You can use any combination of forces and moments.
- Optional:
To apply the load along an inclined coordinate system:
-
Select the
Inclined Load? option.
The force and moment labels are updated with (') to indicate that the loads and moments will act in the inclined axes.
-
Select the method of defining the reference point.
- Reference Node - select an existing node number from the model. The global coordinates of that node are displayed as read-only.
- Absolute - type the global coordinates of an arbitrary point to use as the reference.
- Relative - type relative distances from the loaded joint to the reference point. These distances are measured along the global axes.
Tip: To easily select a reference node with respect to an existing node, first use the Reference Node option to populate the fields with that node's coordinates. Then select the Absolute option to modify the values. For example, you can update the Y coordinate of an existing node to select a point directly above or below that node. - Type the global coordinates (Absolute) or distances (Relative) to the reference point.
-
Select the
Inclined Load? option.
-
Click
Add.
The load item is added to the selected load case.
