PREQUALIFICATION LIMITS
Beam Limitations
Beam depth is limited to a maximum of 36 in. (920 mm) for rolled shapes. The depth of built-up sections does not exceed the depth permitted for rolled wide-flange shapes.
Beam flange thickness is limited to a maximum of 1 in. (25 mm).
The clear span-to-depth ratio of the beam is limited as follows:
For special moment frame systems, 9 or greater.
For intermediate moment frame systems, 7 or greater.
