A solid one-way slab is to be used for a framing system Column spacing is 33 ft, with regularly spaced beams occurring at 11 ft center to center. Superimposed dead load on the structure is 50 psf and the live load is 75 psf. Use fc'= 4ksi and fy'= 60 ksi. Determine the thickness for the slab and select the size and spacing for the bars.
