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
(A) D = W (a - b)/4a²bq
(B) D = W (a² - b²)/4a²bq
(C) D = W (a² - b²)/8a²bq
(D) D = W (a² - b²)/4abq
side b, carrying a weight W including the weight of the footing, the depth (D) of the footing from
punching shear consideration, is
(A) D = W (a - b)/4a²bq
(B) D = W (a² - b²)/4a²bq
(C) D = W (a² - b²)/8a²bq
(D) D = W (a² - b²)/4abq
