To specify a restraint at a joint

§    Select the joint or joints to be restrained

§    Choose Joint Restraint from the Frame menu

A dialog box will appear with a range of icons for the various types of restraint

§    Click on the appropriate restraint icon

§    Click on the OK button

Selecting the "no restraint" icon (the first icon in the list) will remove all joint restraints from the selected joints.  Selecting any other icon will remove any prescribed displacements or springs from the selected joints and replace them with the selected restraint.

Each of the possible restraints is indicated by an icon.  As you click on the icons, the check boxes at the bottom of the dialog will display the degrees of freedom that will be restrained if you select that icon.

You can also click on the check boxes directly to choose which degrees of freedom you wish to restrain.  If the combination of restraints you select is not one of the standard icons, Multiframe will display the special restraint icon (the last icon in the list).

After you have added a restraint to the frame, you can change its properties by double clicking on the restraint icon in the Frame window. You can also edit the individual degrees of freedom of the restraint in the Restraints table in the Data window.
