RCC Structures Design In a doubly-reinforced beam if ‘c’ and ‘t’ are stresses in concrete and tension reinforcement, ‘d’ is the effective depth and ‘n’ is depth of critical neutral axis, the following relationship holds good mc/t = n/(d - n) mc/t = (d - n)/t (m + c)/t = n/(d + n) (t + c)/n = (d + n)/n mc/t = n/(d - n) mc/t = (d - n)/t (m + c)/t = n/(d + n) (t + c)/n = (d + n)/n ANSWER DOWNLOAD EXAMIANS APP

RCC Structures Design ‘P’ is the pre-stressed force applied to tendon of a rectangular pre-stressed beam whose area of cross section is ‘A’ and sectional modulus is ‘Z’. The minimum stress ‘f’ on the beam subjected to a maximum bending moment ‘M’ is f = (A/P) - (M/Z) f = (P/'- (Z/M) f = (P/A) - (M/Z) f = (P/A) - (M/6Z) f = (A/P) - (M/Z) f = (P/'- (Z/M) f = (P/A) - (M/Z) f = (P/A) - (M/6Z) 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
