RCC Structures Design Pick up the incorrect statement from the following: Tensile reinforcement bars of a rectangular beam Are maintained at bottom to provide at least local bond stress Are curtailed if not required to resist the bending moment Are bent down at suitable places to serve as shear reinforcement Are bent up at suitable places to serve as shear reinforcement Are maintained at bottom to provide at least local bond stress Are curtailed if not required to resist the bending moment Are bent down at suitable places to serve as shear reinforcement Are bent up at suitable places to serve as shear reinforcement ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design An R.C.C. beam not provided with shear reinforcement may develop cracks in its bottom inclined roughly to the horizontal at 25° 35° 45° 55° 25° 35° 45° 55° ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If the length of a combined footing for two columns l meters apart is L and the projection on the left side of the exterior column is x, then the projection y on the right side of the exterior column, in order to have a uniformly distributed load, is (where x̅ is the distance of centre of gravity of column loads). y = L/2 - (l - x̅) y = L/2 + (l - x̅) y = L - (l - x̅) y = L/2 - (l + x̅) y = L/2 - (l - x̅) y = L/2 + (l - x̅) y = L - (l - x̅) y = L/2 - (l + x̅) 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 40 35 45 30 40 35 45 30 ANSWER DOWNLOAD EXAMIANS APP
