RCC Structures Design The modular ratio ‘m’ of a concrete whose permissible compressive stress is ‘C’, may be obtained from the equation. m = 700/3C m = 1400/3C m = 2800/3C m = 3500/3C m = 700/3C m = 1400/3C m = 2800/3C m = 3500/3C ANSWER DOWNLOAD EXAMIANS APP
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) (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 ANSWER DOWNLOAD EXAMIANS APP
