RCC Structures Design
If the bearing capacity of soil is 10 tonnes/cm² and the projection of plain concrete footing from walls, is a cm, the depth D of footing is

D = 0.775 a

D = 0.775 a²

D = 0.775 √a

D = 0.0775 a

D = 0.775 a

D = 0.775 a²

D = 0.775 √a

D = 0.0775 a

RCC Structures Design
The modular ratio ‘m’ of a concrete whose permissible compressive stress is ‘C’, may be obtained from the equation.

m = 2800/3C

m = 700/3C

m = 1400/3C

m = 3500/3C

m = 2800/3C

m = 700/3C

m = 1400/3C

m = 3500/3C
