This tool allows you to graphically apply force and moment loads to nodes. Node loads are always referenced to the global axes system. If you wish to apply node loads in local axes you should use member concentrated loads instead (see also Member concentrated loads).
The procedure is as follows.
Select
the nodes you wish to load, click the right mouse button and then
select "Loads" => "Node Loads" from the popup
menu that appears.
OR
Click the toolbar button or select "Node
Loads - Graphical" from the Loads menu, select the nodes you
wish to load, click the right mouse button and then click Ok.
In
the load case form that appears, if you are inputting new loads then
you would probably leave the load cases list field blank and specify
the load cases in the datasheet that follows. If you are editing loads
then you may also wish to leave the load cases list field blank unless
there are a large number of load cases and you want to restrict the
datasheet to just some of them.
You should then choose between showing the loads applied to each selected
node individually (ie. one line of data for each node) or applied
as a group to all the selected nodes (ie. one line of data for all
the nodes). The advantage of the "group" selection is that
you only have to input one line of data in the datasheet to have it
applied to all the selected nodes. This can be particularly useful
if you are applying the same load to a number of nodes. If you are
inputting a different load on each node then you should choose the
"individual" selection. Choosing "individual"
can also be useful if you are simply trying to see what loads are
already applied to the nodes you have selected.
If you have elected to show the loads applied to each node individually
then you can also choose between showing all the selected nodes or
just the ones that are loaded. If you are inputting new loads then
you would probably choose to show all the selected nodes, whereas
if you are editing existing loads or just viewing loads then showing
just the loaded nodes may be preferable.
A
datasheet then appears with any existing loads shown. You can add,
edit or delete loads and then click the Ok button to save any changes.
The operation of the datasheet is the same as the non-graphical datasheets
(see also Datasheets).
Refer to "Using
datasheets" for information on how to operate the above datasheet.
