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
A slab panel is carrying a superimposed dead load of 2.70 kPa and superimposed live load of 6.0 kPa all over the 4.0 m x 18 m light storage area. The slab is restrained. The concrete to be used has strength of 28 MPa (normal weight). The main reinforcement has yield strength of 350 MPa. Use concrete cover of 20 mm. The thickness uses a multiple of 10 mm. The main reinforcement used is 16 mm in diameter The shrinkage and temperature reinforcement used is 12 mm in diameter The unit weight of concrete is 23.6 kN per cubic meter. Using USD, Determine the spacing of 12 mm main rebar at the support.
