## RCC Structures Design The self-weight of the footing, is

Also considered for calculating the upward pressure on footing
Not considered for calculating the area of the footing
Both (b) and (c)
Not considered for calculating the upward pressure on footing

## RCC Structures Design If p₁ and p₂ are mutually perpendicular principal stresses acting on a soil mass, the normal stress on any plane inclined at angle θ° to the principal plane carrying the principal stress p₁, is:

[(p₁ - p₂)/2] + [(p₁ + p₂)/2] cos 2θ
[(p₁ + p₂)/2] + [(p₁ - p₂)/2] sin 2θ
[(p₁ + p₂)/2] + [(p₁ - p₂)/2] cos 2θ
[(p₁ - p₂)/2] + [(p₁ + p₂)/2] sin 2θ
