FATRB

 

Purpose:  Used to specify allowable fatigue stress range in ASD or LFD projects.

 

-->    Given in girder input

 

Allowable fatigue stress range (ksi or MPa) which overrides that determined for Category B fatigue according to Table 10.3.1A.  In this way the user can have the girder designed or rated, say, according to Art. 10.3.3 of the 1989 GUIDE SPECIFICTIONS FOR FATIGUE DESIGN OF STEEL BRIDGES.  (At this time the user is responsible for specifying the parameters in 10.3.3 to determine the allowable stress ranges for the various stress categories.)
