question 9 (a)
9 Design interior one-way slabs for the situations shown. Concrete weight 150 lb/ft3, fy= 60,000 psi, and f c= 4000psi. Do not use the ACI Code's minimum thickness for deflections (Table 4.1). Steel percentages are given in the figures. The only dead load is the weight of the slab. a) WL150 psf 24 ft

Assume normal concrete weight (wc = 143 lb/ft) with specified compressive strength fc = 4,000 psi, and steel Grade 60 (fy = 60,000 psi). For design loads assume dead load wd = 30 lb/ft? (excluding self-weight) and live load we = 100 lb/ft. Finally assume that the steel percentage ratio is equal to p= 0.18fc/fy. Design an interior one-way simply supported slab with a 15 ft span using the above assumptions. Show sketches of one-way slab cross section, including reinforcing...
