Form: Assign Frame Releases
End releases and partial fixity are assigned to selected frame objects:
Select the frame objects to which releases are to be applied.
Click the Assign menu > Frame > Releases/Partial Fixity command to access the Assign Frame Releases form.
For each end of the object, check the type of release desired -- Axial Load, Shear Force 2 (Major), Shear Force 3 (Minor), Torsion, Moment 22 (Minor) and Moment 33 (Major).
Optionally, use the associated edit box to specify a spring constant (force/length or moment/radian) at a release if partial fixity is required.
Note: To specify partial fixity for a particular degree of freedom, that degree of freedom must be released.
If no releases are desired, check the No Releases check box.
Note: The releases specified always replace the existing releases.
Example: Assignment of releases/partial fixity is demonstrated in Problem A
