The axes are what you like. Let you define the principal axis Xinit of 
you beam section in reference coordinate system (which we don't do 
usually, just because we don't need). Then apply 
ScGeom::rotateAndGetShear(X) on it (I should definitely split "rotate" 
and "getShear" for consistency... one more TODO), exactly as we do for 
contact forces. It will keep track of you local X orientation, so that 
you can project everything on it (e.g. fn, fx, fy) in the constitutive law.
