A one way slab has a total depth of 200mm with a 20mm clear cover at the bottom. The steel reinforcement is 20 mm diameter spaced at 125mm on centers. Use f'c = 30 MPa and fy = 400 MPa. 1) Determine the depth of the stress block for a strip of slab. 2) Determine the moment capacity of the strip of slab. 3) Determine the live load per sq.m. that the slab can carry if the slab were used on a 3m simple span. Concrete mass maybe taken at 2500 kg/m³ which includes the weight of reinforcement. Use 2015 NSCP. SDL can be taken as 12 kPa/m.
