5.2 A one-story exterior platform is shown in the following figure. The roof is one-way slab. Answer the following questions (a through i) and design a one-foot wide strip of the roof slab. One-Story Concrete Platform 20-0 -Slab Beam 25-0 b) Determine the minimum slab depth based on ACI Table 9.5(a) 5.1. a) Determine the span length for the slab (assume that the support beams and columns at each end of the slab are 12 inches wide). c) Assume that this slab is 14-inch-thick and it must support 25 psf weight of non-structural equipment and 50 psf code-required live load. Calculate the slab average design loads (in psf). d) Calculate the factored design load: U=1.2DL + 1.6LL
