RCC Structures Design
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

D = W (a² - b²)/8a²bq
D = W (a - b)/4a²bq
D = W (a² - b²)/4abq
D = W (a² - b²)/4a²bq
