What is the correct fiber orientation for the PreVABS 2.0 Box Beam example, +15 or -15 degrees? Text states +15. XML file also shows +15. But Table 11 indicates -15 degrees. Is this a discrepancy or does it relate to the element frame and how the baseline direction is defined?
Per PreVABS 2.0 documentation:
User should pay attention to the relations among the base line direction, elemental frame y and fiber orientation of each layer:
Change of direction of the base line will change the elemental frame y as defined, which will further require the user to change the fiber orientations accordingly, even though nothing changes physically.
