Q. If q is the punching shear resistance per unit area a, is the side of a square footing for a column of side b, carrying a weight W including the weight of the footing, the depth(D) of the footing from punching shear consideration, is (Solved)
1. D = W (a - b)/4a²bq
2. D = W (a² -b²)/4a²bq
3. D = W (a² -b²)/8a²bq
4. D = W (a² - b²)/4abq
- b. D = W (a² -b²)/4a²bq
