RCC Structures Design If T and R are tread and rise respectively of a stair, then R + 2T = 60 2R + T = 60 2R + T = 30 R + 2T= 30 R + 2T = 60 2R + T = 60 2R + T = 30 R + 2T= 30 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 45 40 35 30 45 40 35 ANSWER DOWNLOAD EXAMIANS APP
