RCC Structures Design In a doubly-reinforced beam if ‘c’ and ‘t’ are stresses in concrete and tension reinforcement, ‘d’ is the effective depth and ‘n’ is depth of critical neutral axis, the following relationship holds good (t + c)/n = (d + n)/n mc/t = n/(d - n) (m + c)/t = n/(d + n) mc/t = (d - n)/t (t + c)/n = (d + n)/n mc/t = n/(d - n) (m + c)/t = n/(d + n) mc/t = (d - n)/t ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If Sb, is the average bond stress on a bar of diameter ‘d’ subjected to maximum stress ‘t’, the length of the embedment ‘l’ is given by l = dt/Sb l = dt/2Sb l = dt/4Sb l = dt/3Sb l = dt/Sb l = dt/2Sb l = dt/4Sb l = dt/3Sb 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 45 40 30 35 45 40 ANSWER DOWNLOAD EXAMIANS APP
