Purpose: Used to specify wheel load distribution in ASD or LFD Girder System Projects. (See WHEELS et al. for Line Girder Projects.)
--> Given in girder system input
Wheel distribution factor for interior girders applied to slice of influence surface over each girder instead of directly loading lanes (also applies to live load forces on bracing.) (Also see WHDFAS , WDD-i , WDF-i , WDR-i , WDS-i )
