If P kg/m2 is the upward pressure on the slab of a plain concrete footing whose projection on either side of the wall is a cm, the depth of foundation D is given by-A-D = 0.00775 aPB-D = 0.0775 aPC-D = 0.07775 aPD-D = 0.775 Pa-A-D = 0.00775 aP

Question

APTITUDE CRACK · Accepted Answer

A D = 0.00775 aP To determine the depth of the foundation D for a plain concrete footing under a wall, we need to consider the upward pressure P on the slab and the projection a of the footing on either side of the wall. A common empirical relationship used in foundation design is: D=k&times;a&times;P Where: D is the depth of the foundation, a is the projection of the footing on either side of the wall, and k is a coefficient that depends on the soil properties, foundation type, and other factors. Given that the coefficients k and P are provided in the options, we can substitute them to find the correct expression for D. From the provided options: D=0.00775&times;aP Therefore, the correct expression for the depth of the foundation D is D=0.00775&times;aP.
