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) (t + c)/n = (d + n)/n mc/t = (d - n)/t (m + c)/t = n/(d + n) mc/t = n/(d - n) (t + c)/n = (d + n)/n mc/t = (d - n)/t (m + c)/t = n/(d + n) ANSWER DOWNLOAD EXAMIANS APP
