Any cross section be it I beam, C section or box section can have the same stiffness but the box beam structure is stiffer in bending and torsion than the C section or I beam by weight. Said another way a linear ft of box beam will be lighter than the linear foot of the C or I beam given the same modulus steel. So I think CC ads are valid.
