RCC Structures Design If ‘A’ is the sectional area of a pre-stressed rectangular beam provided with a tendon pre-stressed by a force ‘P’ through its centroidal longitudinal axis, the compressive stress in concrete, is 2A/P A/P P/2A P/A 2A/P A/P P/2A P/A ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If a rectangular pre-stressed beam of an effective span of 5 meters and carrying a total load 3840 kg/m, is designed by the load balancing method, the central dip of the parabolic tendon should be 5 cm 20 cm 15 cm 10 cm 5 cm 20 cm 15 cm 10 cm ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design Though the effective depth of a T-beam is the distance between the top compression edge to the centre of the tensile reinforcement, for heavy loads, it is taken as 1/16th of the span 1/8th of the span 1/12th of the span 1/10th of the span 1/16th of the span 1/8th of the span 1/12th of the span 1/10th of the span ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If R and T are rise and tread of a stair spanning horizontally, the steps are supported by a wall on one side and by a stringer beam on the other side, the steps are designed as beams of width R - T √(R² + T²) R + T T - R R - T √(R² + T²) R + T T - R 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 40 45 35 30 40 45 35 ANSWER DOWNLOAD EXAMIANS APP
