M. To create a reference load
To define a reference load and add it to a reference load item, use the following procedure.
A reference load case allows you to construct a load case with load items but it will not be directly solved by the analysis engine. It is only solved when it is called by another load case. This allows you to limit the number of load cases analyzed.
- In the Load & Definition dialog, select the entry and then click Add. The Add New Reference Load Definitions dialog opens.
- (Optional) Type a Number for the load case. The program will increment the load case number based on existing load case numbers.
- (Optional) Select the Loading Type. This selection is used when automatically generating load combinations. If you select a live load type, you may also indicated if the load is Reducible per UBC/IBC.
- Type a Title used to easily identify this load case.
- Click Add. The reference load definition is added to the entry in the Load & Definition dialog.
Add load items to the reference load definition.
This is done similar to how you would add load items to a primary
load case. Reference load definitions can contain:
- selfweight loads
- nodal loads
- member loads
- physical member loads
- area loads
- floor loads
- plate loads
- surface loads
- solid loads
- temperature loads
Tip: This will add the load item to the currently selected load group selected in the program status bar.
- Select the A list of the reference load definitions is in the Available Load Cases list. tab.
- Repeat Step 9 to add additional reference load definitions to the Reference Load item.
- (Optional) Type a Factor to apply to each reference load definition in the Reference Load item as needed.
- Click Add.
