Purpose: Used to locate box girder internal braces in Girder System Projects. (Corresponding BR data is generated in girder input in Girder System Projects. Internal braces are to be included in BR data in Line Girder Projects.)
--> Given in girder system input
A list of spacings between the struts of the internal horizontal truss bracing of the top flanges for box girder "i" (feet or meters). The location of internal vertical cross frames with respect to the struts is defined with the SCRATI0 command. Even if the internal bracing is radially located across all girders, these spacings must be given for each girder.
(Note: Internal bracing must be present at external bracing locations, and so INB-i must include these locations.)
