Live Load Category [Gravity/Gravity and Centrifugal/Centrifugal/Hunting/ Braking]:
Unit Load Spacing Long.: The spacing of the unit loads in both longitudinal and transverse directions significantly affects the total analysis time. For each unit load, a finite element analysis must be conducted. This parameter allows the user to specify the unit load spacing in the longitudinal direction.
Centrifugal
The parameters listed below, part of this tab, are applicable only if the Live Load Category parameter (under the General Tab) is set to either 'Gravity and Centrifugal' or 'Centrifugal.' Otherwise, these parameters will be marked as Not Applicable (N/A).
Centrifugal Factor Comp. Method [User Defined/AREMA 1.3.6.c]: The centrifugal factor can be calculated according to the AREMA specification or manually defined by the user through the parameter options.
Max. Design Speed:
Centrifugal Factor:If the Centrifugal Factor Comp. Method parameter is set to 'User Defined,' this parameter can be specified. Otherwise, since the centrifugal force factor will be calculated according to AREMA, it will be shown as Not Applicable (N/A).
Height of Application Point (from rail):

Hunting
Hunting Force Factor: The hunting force factor can be specified manually by the user using this parameter.
