9.A rectangular footing supports a square column concentrically.
Given: Footing Dimensions: 2.5m wide x 4.0m long and 0.80m depth Column Dimensions: 0.45m x 0.45m Concrete, fc’ = 28MPa Steel, fy = 415MPa Concrete cover to the centroid of steel reinforcements = 100mm Unit weight of concrete = 24kN/m3 Unit weight of soil = 17kN/m3
a. Determine the concentrated load that the footing can carry based on beam action.
b. Calculate the concentrated load that the footing can carry based on two-way action.
c. If the allowable soil pressure at service loads is 210kPa, what column axial load (unfactored) in kN can the footing carry if depth of earth fill is 2m above the footing?
