• In the Type area select the Force-Displacement option. This controls whether the data in
the spreadsheet and the acceptance criteria are interpreted by the program as forcedisplacement
or stress-strain. The stress-strain option is only available for axial and shear
hinges (uncoupled).
Note: When the Type option is set to stress-strain, a hinge length must be input. The
hinge length can be input as an absolute length or a relative length. The relative
length is relative to the clear length of the frame element between rigid end
offsets. If the stress-strain option is chosen, the program internally transforms the
data into a force-displacement format for analysis. The force is calculated as the
stress times the frame member axial area (σA) for axial hinges and the stress
times the frame member shear area (σA V ) for shear hinges. The displacement is
calculated as the strain times the hinge length (εL).
• Click the OK button three times to accept the USER hinge property definition.
• We will now delete the USER hinge property since we are not going to use it.
• From the Define menu choose Hinge Properties…. This will display the Define Frame
Hinge Properties dialog box.
• Highlight the USER hinge property and click on the Delete Property button. Click the
Yes button when the program asks if it is OK to delete Frame Hinge USER from list.
• Click the OK button to accept the change in hinge properties and exit the Define Frame
Hinge Properties dialog box.
Note: If you click the Cancel button the property will not be deleted.
This completes the review of defining hinge properties.
