Form: Cable Temperature Loading
The temperature load creates thermal strain in the cable object. This strain is given by the product of the material coefficient of thermal expansion and the temperature change of the object, which is the temperature being specified here
Select one or more cables to be assigned a temperature load.
Click the Assign Loads > Cable Loads > Temperature command to access the Cable Temperature Loading form.
Load Case Name drop-down list. Select the load case to which the load is being assigned. 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.
Type.
Temperature option. The program applies the temperature load as a constant through the thickness of the cable and produces membrane strains.
Temperature. Choose if the temperature is to be applied by element or by joint pattern:
By Element. If by element, specify a value in the Temperature edit box.
By Joint Pattern. If by Joint Pattern, choose a pattern from the Pattern drop-down list and specify a value in the Multiplier edit box.
Option. Specify how the load is to be applied.
Add to Existing Loads: Adds the specified temperature load to the selected object. If one or more temperature load assignments have already been made, this option increases the existing load, assuming a positive load is being specified.
Replace Existing Loads: Replaces the currently specified temperature load, if any, with the new load. If no assignment exists, the new assignment is still made. This is the default option.
Delete Existing Loads: Deletes any and all temperature load assignments made to the selected object(s). When this option is selected, the items in the Type and Temperature areas 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.
Example: Use of this command is demonstrated in Problem V.
