BR-i

Purpose: Used to locate intermediate bracing in parallel/concentric geometry Girder System Projects. (Not applicable to Line Girder Projects.)

--> Given in girder system input

Lists of bracing spacings for girder "i" (feet or meters). For example, BR-1 is a list of the brace spacings along girder 1 for bracing between girder 1 and girder 2. If only BR-1 is given, bracing will be made collinear/radial across the girder system. In the case of box girders, BR-i only represents spacing of bracing that is external to the box cells. (The data item INB-i is used for bracing locations internal to the box girders.)

BR-2 and above only are given for bracing from girder "i" to girder "i+1" when bracing is staggered.

Bracing is automatically assumed between supports of adjacent girders. To remove the bracing along interior supports, see the condition NO BRACING ALONG PIERS.
