4. An interior reinforced concrete slab has to be designed to support a live load and a dead load in addition to its own weight based on the following specifications: The slab is one-way and simply supported with a span of 12 ft. The live load on the slab is 200 psf. The dead load on the slab is 100 psf. Your design will use concrete compressive strength fe= 3000 psi and steel yield strength of fy = 40,000 psi
