Question
A 400 mm x 400 mm column carries a total dead
load of 1150 kN and a total live load of 770 kN. The
column is to be supported by a rectangular spread
footing having thickness of 675 mm whose width is
limited to 3 m. The net soil bearing capacity of the
soil is 215 kPa. For footing, use f'c = 24 MPa and
for column, use f'c = 20.7 MPa. Use fy = 414 MPa
for all steel bars. Use 75mm concrete cover.
11. Determine the length of the footing.
12. Determine wide beam shear stress at the
critical section.
13. Determine the punching shear stress at the
critical section.
14. Design the reinforcements using 25 mm bars,
determine the number of reinforcements along the
long direction.
15. Design the reinforcements using 25 mm bars,
determine the number of reinforcements along the
short direction.
