A reinforced concrete building floor system consists of a continuous one-way slab built monolithically with its supporting beams, as shown in cross section in Fig. P13.2. Service live load will be 125 psf. Dead loads include a 10 psf allowance for nonstructural lightweight concrete floor fill and surface, and a 10 psf allowance for suspended loads, plus the self-weight of the floor. Using ACI coefficients from Chapter 12, calculate the design moments and shears and design the slab, using a maximum tensile reinforcement ratio of 0.006. Use all straight bar reinforcement. One-half of the positive-moment bars will be discontinued where no longer required; the other half will be continued into the supporting beams as specified by the ACI Code. All negative steel will be discontinued at the same distance from the support face in each case. Summarize your design with a sketch showing concrete dimensions, and size, spacing, and cutoff points for all reinforcement. Material strengths are f, 60,000 psi and f = 3000 psi. 16'-0" 16'-0" End span Typical interior span 26" 18" 18" 18"
