Purpose: Used to indicate supports that are integral with abutments/piers in Girder System Projects.
--> Given in girder system input
A list indicating which supports on girder "i" are fixed against rotation. A "1" in the list represents fixity and a "0" represents rotational freedom. (Also see INTEGRAL ABUTMENTS and ITGSUP).
