 A one-way solid slab of a span of 3000 mm and a total thickness, h, of 150 mm is subjected to a service L.L. of 9.58 kN/m2. The concrete compressive strength, f'c , is 20.7 MPa, the steel yielding strength, fy , is 414 MPa, the total cover of steel is 30 mm, minimum reinforcement ratio is ρmin = 0.0033, maximum  reinforcement ratio is ρmax = 0.0135, and density of concrete γc = 24 kN/m3. What is the required area of steel reinforcement, As,req., needed to resist the ultimate bending moment? urgent answer please

Area of steel required to resist moment developed is calculated.

Calculated area of steel is checked for minimum and maximum steel ratio.
