A 200 mm wide concrete block wall carries a vertical dead load of 120 kN/m and a verticallive load of 88 kN/m. The expected sustained load for serviceability is 160 kN/m. The wallis to be supported on a continuous spread footing that is to be founded at a depth of at least500 mm below the ground surface. The geotechnical design for the project was done usingASD and determined the allowable bearing pressure based on bearing capacity as 310 kPa andthe allowable bearing pressure to meet settlement requirements as 155 kPa. The groundwatertable is at a depth of 10 m. Develop a structural design for this footing using f′ c = 15 MPa and grade 280 steel, fy = 280 MPa.

Question
A 200 mm wide concrete block wall carries a vertical dead load of 120 kN/m and a vertical
live load of 88 kN/m. The expected sustained load for serviceability is 160 kN/m. The wall
is to be supported on a continuous spread footing that is to be founded at a depth of at least
500 mm below the ground surface. The geotechnical design for the project was done using
ASD and determined the allowable bearing pressure based on bearing capacity as 310 kPa and
the allowable bearing pressure to meet settlement requirements as 155 kPa. The groundwater
table is at a depth of 10 m. Develop a structural design for this footing using f′
c = 15 MPa and
grade 280 steel, fy = 280 MPa.
