Purpose: Used to indicate whether bracing is present along interior piers in parallel/concentric geometry Girder System Projects. (Not applicable to Line Girder Projects.)
--> Given in girder system input
Designates interior piers along which there is no bracing, where 0’s indicate bracing is along pier and 1’s indicate no bracing is along pier. For example, a seven span bridge with the following:
NBPIER 0 0 0 1 1 0
indicates there is no bracing along support lines 5 and 6. (Also see condition NO BRACING ALONG PIERS )
