Problem 2. The one-way slab, S1 (typ.), has a thickness of 5-in, cast with fe =5,000 psi (normal weight concrete, 150 pcf. Bi = 0.8). No. 4 Gr-60 rebars are used as main (i.e., longitudinal) reinforcement, and No. 3 Gr-60 rebars are secondary (.e., temperature and shrinkage, perpendicular to main) reinforcement with a standard cover of %-in. No shear reinforcement is provided. The floor is subjected to a live load of 50 psf.
(10 points) Compute per AC1318 the design flexural capacity (OM) per linear ft of slab for positive moment region of the slab, if it is reinforced with No. 4 Gr-60 rebars at 10" on-center spacing
