Question

What is the vertical induced stress (Adz) at a point 1.5 m below the center of the footing using Hari Method?

a) ( Adz = P ⋅ B ⋅ (1 - ν)/2 ⋅ π ⋅ (1 + ν) ⋅ √(r² + H²) )

b) ( Adz = P ⋅ B/2 ⋅ π ⋅ √(r² + H²) )

c) ( Adz = P ⋅ B ⋅ (1 - ν)/π ⋅ √(r² + H²) )

d) ( Adz = P ⋅ B/π ⋅ √(r² + H²) )

Answer 1

The vertical induced stress at a point below the center of a footing can be calculated using the Hari method.

Step-by-step explanation:

The vertical induced stress at a point below the center of a footing can be calculated using the Hari method. The formula is given as:

Adz = P ⋅ B ⋅ (1 - ν)/2 ⋅ π ⋅ (1 + ν) ⋅ √(r² + H²)

Where:

• Adz is the vertical induced stress
• P is the applied load on the footing
• B is the width of the footing
• ν is the Poisson's ratio of the soil
• r is the horizontal distance from the center of the footing to the point
• H is the vertical distance from the center of the footing to the point

In this case, we are given the formula option (a) Adz = P ⋅ B ⋅ (1 - ν)/2 ⋅ π ⋅ (1 + ν) ⋅ √(r² + H²)
