The maximum Mu is 72 kip-ft for a 12 in. thick one-way slab. f'c = 6000psi and clear cover is 2 in. if you use no. 8 bars (Grade 75), what bar spacing should you specify to provide adequate flexural strength?

B. Design an interior one-way slab considering the given loading. The weight of the slab is not included in the given loading. Include a reasonable estimate for the slab weight. Use Pmax = 0.18 fc/fy. Choose a es not exceed twice the thickness of the slab. Show sketch of cross section including bars sizes and spacing. Assume normal weight concrete that weighs 150 pcf, fy = 60,000 psi, fc = 4,000 psi. W. = 100 psf

Using Principles of Structural Design 2nd Edition... A 81/2 in. thick one-way slab interior spans 10 ft. It was designed with the reinforcement of #6 size bars at 6.5in. on center, to be placed with a cover of 0.75in. However, the same steel was misplaced at a clear distance of 2in. from the bottom. How much is the reduction in the capacity of the slab reduced to carry the superimposed live load in addition to its own weight? f'c=4,000 psi,...

A simply supported one-way slab of 12 ft span and 8-inch thick is given. The rebar used in the slab is #8 at 6 inches on center. Determine how much live load (psf) may the slab safely carry. (f'c=3,000 psi, fy=40,000 psi).

Design a simple-span, one-way slab to carry a uniformly distributed live load of 375 psf plus the self-weight of the slab. The span is 10-ft., center-to-center of the supports. Assume fe' = 4,000 psi and fy = 60,000 psi. Design per foot of width. Use #5 bars for both longitudinal and temperature and shrinkage reinforcement. (30 pts.)

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...

A 5 in thick simply supported
reinforced concrete one-way slab is part of a roof system. It is
supported by two masonry block walls, as shown below. Assume a
superimposed dead load (roofing, insulation, ceiling, etc.) of 15
psf and a roof live load of 30 psf. Check the adequacy of the slab,
including the required shrinkage and temperature reinforcement. Use
= 4,000 psi and = 60,000 psi.
