Problem 4: (15%) Consider a 7 inch thick simply supported slab with a span of 12...
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).
You are given the task of checking the adequacy of a simply supported slab of 10-inch thickness, 12 ft span. The reinforcement used is #7 rebar at 6 inches on center. The distributed live load on the slab is 600 psf respectively. Assume f’c=3,000 psi, fy=60,000 psi. Determine if the slab is structurally sufficient, and post your detail calculations as well.
Problem Two: The beam shown below part is for an interior span and is cast monolithically with a one-way slab. The clear span for the beam is 30 feet, and the clear spacing between beams is 10 feet. (a) Reinforcement is shown for the positive moment region. Determine if the beam is adequate to support a uniformly distributed, factored load of 5 k/ft. (b) Design the slab reinforcement for the positive moment region using a factored load of 500 psf....
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. 1.
