Part 2: Concept Design 2 - 34 225 300 - 350 5 - 9 m 6 - 9 m (1) (2) (3) 1 Integrated beam 2 Tie member 3 Deep composite slab or hollow core concrete slab Figure 4.9 Integrated beams or slim floor (span of slab is indicated) The span range of various structural options in both steel and concrete are illustrated in Figure 4.10. Long span steel options generally provide for service integration for spans of over 12 m. Ce llular beams and composite trus ses ar e more efficient for long span secondary beams, whereas fabricated beam s are often used for long span primary beams.
