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

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).

1. 0.5 meter
2. 1 meter
3. 1.5 meter
4. 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
