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 (a - b)/4a²bq D = W (a² - b²)/4abq D = W (a² - b²)/8a²bq D = W (a² - b²)/4a²bq D = W (a - b)/4a²bq D = W (a² - b²)/4abq D = W (a² - b²)/8a²bq D = W (a² - b²)/4a²bq ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If ‘p’ is the net upward pressure on a square footing of side ‘b’ for a square column of side ‘a’, the maximum bending moment is given by M = pb (b - a)²/4 M = pb (b - a)²/8 M = pb (c - a)/4 M = pb (b + a)/8 M = pb (b + a)/8 M = pb (b - a)²/4 M = pb (b - a)²/8 M = pb (c - a)/4 M = pb (b + a)/8 M = pb (b + a)/8 ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design ‘P’ is the pre-stressed force applied to the tendon of a rectangular pre-stressed beam whose area of cross section is ‘A’ and sectional modulus is ‘Z’. The maximum stress ‘f’ in the beam, subjected to a maximum bending moment ‘M’, is f = (P/A) + (M/Z) f = (A/P) + (M/Z) f = (P/'+ (Z/M) f = (P/A) + (M/6Z) f = (P/A) + (M/Z) f = (A/P) + (M/Z) f = (P/'+ (Z/M) f = (P/A) + (M/6Z) ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design A reinforced concrete cantilever beam is 3.6 m long, 25 cm wide and has its lever arm 40 cm. It carries a load of 1200 kg at its free end and vertical stirrups can carry 1800 kg. Assuming concrete to carry one-third of the diagonal tension and ignoring the weight of the beam, the number of shear stirrups required, is 30 35 40 45 30 35 40 45 ANSWER DOWNLOAD EXAMIANS APP
