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)/4a²bq

D = W (a² - b²)/4abq

D = W (a² - b²)/8a²bq

D = W (a - b)/4a²bq

D = W (a² - b²)/4a²bq

D = W (a² - b²)/4abq

RCC Structures Design
With usual notations the depth of the neutral axis of a balanced section, is given by

mc/t = n/(d - n)

mc/t = (d - n)/n

t/mc = (d - n)/n

t/mc = (d + n)/n

mc/t = n/(d - n)

mc/t = (d - n)/n

t/mc = (d - n)/n

t/mc = (d + n)/n
