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 (m + c)/t = n/(d + n) mc/t = n/(d - n) mc/t = (d - n)/t (t + c)/n = (d + n)/n (m + c)/t = n/(d + n) mc/t = n/(d - n) mc/t = (d - n)/t (t + c)/n = (d + n)/n ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If W is total load per unit area on a panel, D is the diameter of the column head, L is the span in two directions, then the sum of the maximum positive bending moment and average of the negative bending moment for the design of the span of a square flat slab, should not be less than WL/12 (L - D/3)² WL/10 (L + 2D/3)² WL/10 (L - 2D/3)² WL/12 (L - 2D/3)² WL/12 (L - D/3)² WL/10 (L + 2D/3)² WL/10 (L - 2D/3)² WL/12 (L - 2D/3)² ANSWER DOWNLOAD EXAMIANS APP
