Plate End Release
Enter the nodal connection conditions (Hinge, Fixed Joint) for plate elements, or replace or remove previously entered end release conditions.
From the Main Menu select Boundary > Release/Offset > Plate End Release.
Click 
to the right of Plate End Release:
Display the Plate End Release Table
Boundary Group
Name
Select a Boundary Group in which
the specified boundary condition is included. Select "Default"
if Group assignment is unnecessary. Click
to the right to prompt the "Define
Boundary Group" dialog box to add, modify or delete Boundary
Groups.
Options
Add/Replace: Enter or replace nodal end release conditions for plate elements
Delete: Delete previously entered nodal end release conditions for plate elements
End Release
Enter nodal end release conditions for selected plate elements with respect to the element's local coordinate system.
Fx: Release axial stiffness of the relevant node in the element's local x-direction.
Fy: Release axial stiffness of the relevant node in the element's local y-direction.
Fz: Release shear stiffness of the relevant node in the element's local z-direction.
Mx: Release bending stiffness of the relevant node about the element's local x-axis.
My: Release bending stiffness of the relevant node about the element's local y-axis.
The following buttons simplify the individual data entries described above:
: Release nodal stiffness of all degrees of freedom. Individual
components can be subsequently fixed.
: Restore all nodal stiffness to Fixed conditions
