A slab with S/L = 0.40 has a thickness of 150 mm reinforced with 12 mm - diameterdeformed bars at spacing s = 200 mm on center. Assume f'c = 28 MPa and fy = 415MPa. Use clear cover of 20 mm. What is the governing steel ratio?
Compute moment of resistance of a one-way slab of thickness 150 mm. The slab is reinforced with 10 mm diameter bars at 200 mm C/C. Use f'c=20 MPa and fj= 420 MPa.
Please write the complete solution neatly.
Notes:
If the calculated minimum thickness of the slab is less than 100 mm, you may consider using 100 mm as your slab thickness. If you will use a thickness less than 100 mm (as calculated using the formula), that is theoretically correct because the National Structural Code allows us to do so.
