Purpose: Used to apply Minnesota DOT exceptions to AASHTO in LRFD projects. (Not applicable to ASD or LFD projects)
--> Given in girder input and girder system input.
Lane fractions determined by the tables in Chapter 4 of the LRFD specification are not to be determined by the special analysis approach described in that chapter, and the correction for skew is to apply to the entire half of the end spans of all girders instead of just the obtuse corner of the exterior girder.
The default truck-train negative moment and reaction factor is set to 1.10.
