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.
(10 points) What is nearly the amount of temperature and shrinkage reinforcement required per linear ft of the slab. Note No. 3 Gr-60 rebars are used. Round the spacing to the near y-in.
