Given: a. bw = 1 ft; b. fc = 4000 psi and fy = 60 ksi. c. Central floor beam spanning in horizontal direction. d. The floor system has a uniform spacing between beams. HINT: For a typical floor system, mid-span sections are subjected to positive bending. Section A-A has a large compression zone: hence compression steel may not be required for additional moment strength in this case. Assuming section will include No. 3 or No. 4 stirrups (compression steel in the section is not shown in the figure which is placed for reinforcement continuity requirements), d-24 in- 3.5 in= 20.5 in and d=24 in-2.5 in = 21.5 in). 7 Slab thickness=5 in. 24 t Figure 1 Continuous Floor System 10 ft 10 ft 3 No. 5 bars b- 72 in No. 7 bars 12 in.
