RCC Structures Design
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)/4a²bq
D = W (a - b)/4a²bq
D = W (a² - b²)/4abq
D = W (a² - b²)/8a²bq

RCC Structures Design
In a singly reinforced beam

Steel possesses initial stresses when embedded in concrete
Compression is borne entirely by concrete
Elastic moduli for concrete and steel have different values within the limits of deformation of the beam
Plane sections transverse to the centre line of the beam before bending remain plane after bending
