Q. The load on a RCC column is 150 kN. The soil bearing capacity is 80 kN/m2. Assuming a factor of safety of 1.2, the side of the square column footing is________________ meter (rounded off to one decimal place).
- 0.5 meter
- 1 meter
- 1.5 meter
- 2.5 meter
Explanation:
Load on column = 150 kN
Design load considering factor of safety = 150 × 1.2 = 180 kN
Soil bearing capacity = 80 kN/m2
Area of footing required =180/80=2.25 sq m
Side of footing = √2.25 = 1.5 meter
