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 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/10√Q M/100Q √(M/100Q) √(M/Q) M/10√Q M/100Q √(M/100Q) √(M/Q) ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design The modular ratio ‘m’ of a concrete whose permissible compressive stress is ‘C’, may be obtained from the equation. m = 3500/3C m = 1400/3C m = 2800/3C m = 700/3C m = 3500/3C m = 1400/3C m = 2800/3C m = 700/3C ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design The width of the rib of a T-beam, is generally kept between 1/2 to 3/4 of rib depth 1/3 to 2/3 of rib depth 1/3 to 1/2 of rib depth 1/7 to 1/3 of rib depth 1/2 to 3/4 of rib depth 1/3 to 2/3 of rib depth 1/3 to 1/2 of rib depth 1/7 to 1/3 of rib depth ANSWER DOWNLOAD EXAMIANS APP
