A six inch thick one-way RC slab (hf =6 inch) is made of fc =4000.0 psi concrete with Gr. 60 #4 bars spaced 8 inch on center for longitudinal reinforcement. The bottom side of the slab has 3/4 inch clear cover. 8 inch 1 ft hf =6 inch Compute the following quantities for a typical 1 ft wide slab design strip. 1. The dead load, wD (lb/ft), of the slab design strip. Assume the concrete is normal- weight and supports a superimposed dead load of 25.0 psf. 2. The live load, wL (lb/ft), of the slab design strip. Assume the slab supports a live load of 60.0 psf. 3. The design flexural strength, Mn (kip-ft) 4. The design shear strength, Vn (kip) 5. Can the slab support its self-weight and loads over a span length of 8 ft? Explain
