Problems 2 and 3 refer to the floor plan shown in Fig. 2. S ci C2 C3 C4 CS GI (typ.) со C7 C8 Given: L = 25' (typ.) and S = 10 (typ.). So, the overall floor plan = 75' x 60 The beam width (bw) and depth (h) of B1 (typ.) are taken to be 10-in and 20-in, respectively L $1 (typ) B1 (typ) B1 (typ) C9 CIO сіп C12 A typical girder, e.g., G1, has a width (bw) of 12-in.

a Problem 2. The one-way slab, S1 (typ.), has a thickness of 5-in, cast with fé = 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 (i.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.
(b) (10 points) The design shear capacity (V.) per linear ft of the slab is nearly? (c) (10 points) Compute per AC1318 the minimum flexural reinforcement required (i.e., As min) per linear ft of slab. 28
