RCC Structures Design If the maximum bending moment of a simply supported slab is M Kg.cm, the effective depth of the slab is (where Q is M.R. factor) M/100Q M/10√Q √(M/100Q) √(M/Q) M/100Q M/10√Q √(M/100Q) √(M/Q) ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If permissible working stresses in steel and concrete are respectively 1400 kg/cm² and 80 kg/cm² and modular ratio is 18, in a beam reinforced in tension side and of width 30 cm and having effective depth 46 cm, the lever arms of the section, is 37 cm 39 cm 38 cm 40 cm 37 cm 39 cm 38 cm 40 cm 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 R + T T - R √(R² + T²) R - T R + T T - R √(R² + T²) 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 - (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) y = L/2 - (l - x̅) y = L/2 - (l + x̅) ANSWER DOWNLOAD EXAMIANS APP
