LVF-i

Purpose: Used to define LRFD lane fraction for shear fatigue.

--> Given in girder system input

List of values for LRFD lane fractions by tenth point for shear fatigue if distribution is used for loading instead of lane definition. A single value given for girder i will be used for the entire girder. A lane is two wheels, thus a value of 0.9 for LVF-i would correspond to 1.8 wheels. If any of LM-i , LV-i , LMF-i , LVF-i or LD-i is given, all must be given.
