Purpose: Used to specify whether Appendices A6.1 and B6.2 are to be applied.
--> Given in LRFD girder input
A list of values in degrees, one for each reaction on girder. Used to declare whether A6.1 and B6.2 in LRFD are to be considered for each support. Measured counterclockwise from the axis of the girder. Default is 90 degrees (no skew).
If the value for a given support is within the guidelines of A6.1 and B6.2, then these Appendices will be considered.
(Note: These Appendices have qualitative considerations in addition to the skew angle, but the program operates simply by the angles that are given to be a declaration of whether these Appendices are to be applied.)
