RCC Structures Design In a pre-stressed beam carrying an external load W with a bent tendon is having angle of inclination ? and pre-stressed load P. The net downward load at the centre is W - 2P sin θ W - 2P cos θ W - P cos θ W - P sin θ W - 2P sin θ W - 2P cos θ W - P cos θ W - P sin θ 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/3Sb l = dt/Sb l = dt/4Sb l = dt/2Sb l = dt/3Sb l = dt/Sb l = dt/4Sb l = dt/2Sb 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
