The self-weight of the footing, is A. Not considered for calculating the upward pressure on footing B. Also considered for calculating the upward pressure on footing C. Not considered for calculating the area of the footing D. Both (B) and (C)

The correct answer is: B. Also considered for calculating the upward pressure on footing.

The self-weight of the footing is the weight of the footing itself, including the weight of the soil it supports. It is a significant factor in calculating the upward pressure on the footing, as it contributes to the total load that the footing must support.

The area of the footing is also a factor in calculating the upward pressure, as it determines the amount of soil that the footing will support. However, the self-weight of the footing is not considered when calculating the area of the footing.

Here is a more detailed explanation of each option:

• Option A: Not considered for calculating the upward pressure on footing. This is incorrect, as the self-weight of the footing is a significant factor in calculating the upward pressure.
• Option B: Also considered for calculating the upward pressure on footing. This is correct, as the self-weight of the footing is a significant factor in calculating the upward pressure.
• Option C: Not considered for calculating the area of the footing. This is correct, as the self-weight of the footing is not considered when calculating the area of the footing.
• Option D: Both (B) and (C). This is the correct answer, as the self-weight of the footing is both considered for calculating the upward pressure and not considered for calculating the area of the footing.
