The layout of a reinforced concrete floor is shown below. The live load is 3 kPa. Design suitable reinforcement for the slab. Take fc’ = 32Mpa. Assume the slab is supported in four sides. Use N 12 bar as reinforcement. Cover is 30mm N12 bar. Assume the slab thickness is 350mm Long term deflection factor is 0.4 and short term deflection factor is 0.7 Column is 300mm x 300mm Beams are 600mm x 300mm including the slab thickness Live load is 3kPa Ec=30100MPa K4 is 1.75 k3 is 1 βx=0.07 βy=0.035 Fsy=500MPa Check the slab thickness is adequate for S1 shown in figure. It means please calculate the minimum total depth (D) value with unit mm. (The most economic depth )(Number with 2 decimal only)

Question
The layout of a reinforced concrete floor is shown below. The live load is 3 kPa. Design suitable reinforcement for the slab. Take fc’ = 32Mpa. Assume the slab is supported in four sides. Use N 12 bar as reinforcement.
- Cover is 30mm N12 bar.
- Assume the slab thickness is 350mm
- Long term deflection factor is 0.4 and short term deflection factor is 0.7
- Column is 300mm x 300mm
- Beams are 600mm x 300mm including the slab thickness
- Live load is 3kPa
- Ec=30100MPa
- K4 is 1.75 k3 is 1 βx=0.07 βy=0.035
- Fsy=500MPa
Check the slab thickness is adequate for S1 shown in figure. It means please calculate the minimum total depth (D) value with unit mm. (The most economic depth )(Number with 2 decimal only)
