SPEED

 

Purpose:  Used to define design speed in Girder System Projects.  (Not applicable to Line Girder Projects.) 

 

-->    Given in girder system input

 

Design speed (mph or kmph) for determining centrifugal force effects in live loading.  If both design speed and superelevation data (see SUPER and SUPERL ) are not given, centrifugal force effects will not be considered.

 

Note: If wheel distribution factors are specified (see WHDINT , WHDFAS , WDD-i , WDF-i , WDR-i , WDS-i ) these factors must account for centrifugal force to include centrifugal force effects.
