Purpose: Used to specify theta for moment reduction due to skew.
--> Given in LRFD line girder input
A list of values in degrees, one for each reaction on girder. Default is 0 degrees. Used to apply moment reduction in determining lane fractions. Always given as a positive angle, regardless of which way it is measured from the perpendicular to the girder cross section.

(Note: This angle is applied as the theta in the formula in Table 4.6.2.2.2e-1)
