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________?
AD = W (a2 – b2)/4a2bq
BD = W (a2 – b2)/8a2bq
CD = W (a2 – b2)/4abq
DD = W (a – b)/4a2bq
Correct answer
A. D = W (a2 – b2)/4a2bq
Explanation
The correct answer is D = W (a2 – b2)/4a2bq.
