SUPERL

 

Purpose:  Used to define superelevation in Girder System Projects. 

 

-->    Given in girder system input

 

A list of superelevations (ft./ft. or m/m) given by tenth point and lanes.  Always given as positive values (correct slope direction will automatically be determined depending on the direction of curvature.)  All values must be given.  For example, the list for a three-lane two-span bridge having superelevation of .04 for the entire length of Lane 1, .045 for Lane 2, and .05 for Lane 3 would be given as:

 

                       SUPERL 21*.04 21*.045 21*.05

 

If design speed (see SPEED ) and superelevation data are not given, centrifugal force effects will not be considered.  (Also see SUPER )

 

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