IBC Table 601 gives the required fire-resistance ratings in hours. Which primary building elements constitute the structural frame specified by these requirements?
I. lateral bracing, II. roof framing, III. columns, IV. stairways, V. girders, beams, VI trusses
A. III, V, VI, B. I, III, V, C. I, II, III, V, VI, D. II, III, V
A. is correct. Only major elements that frame directly into the columns are included as structural frame + designed to carry gravity loads. II. is a secondary element. I. does not meet this criteria, but is usually still fire-protected.
