Good question! 2010 says 3 to 7.5 feet also. I checked the ROP for next edition and did not see any thing about it. Technically if the beams are less than 3' it is not Beam and Girder. Panel Construction does not have the 3' min., but if it exceeds 300 S.F. it is not obstructed. Very curious situation, I hope someone can shed some light.
