T.1 Specifying Supports

The boundary conditions of this problem call for restraining all degrees of freedom at node 1 (FIXED support) and a pinned type of restraint at node 4 (restrained against all translations, free for all rotations).

The STAAD input file commands generated are:

  1. On the Select ribbon tab, select the Node Cursor tool in the Cursors group.

  2. In the View window, click on nodes 1 to select it.
    Note: The Node Tools ribbon tab opens when nodes are selected.
  3. On the Node Tools ribbon tab, select the Assign Supports tool in the Model dialog.

    The Supports - Whole Structure dialog opens.

  4. In the Supports dialog, click Create.

    The Create Support dialog opens.

  5. Select the Fixed tab (selected by default) and then click Assign.

    This creates a FIXED type of support at node 1 where all 6 degrees of freedom are restrained.

  6. To create a PINNED support at node 4, repeat steps 2 through 5, except for selecting node 4 and selecting the Pinned tab in the Create Support dialog.
