Q10. Four columns of building are to be located within a plot size of 10m ×10m . The
expected load on each column is 400 kN. Allowable bearing capacity of soil
deposit is 2 100kN / m2 . The type of foundation to be used is
Answer : Option A
Explaination / Solution:
Load on each column = 400kN
Bearing capacity of soil = 100 kN/m2
Area of each footing required = 400/100m2 = 4m2
Total area required = 4×4 = 16m2
Foundation area/Plot area = 16/100 = 16%
If the foundation area is less than 40% of plot area, then isolated foundation is
suitable.
