RCC Structures Design A pre-stressed concrete member is preferred because All listed here Large size of long beams carrying large shear force need not be adopted Removal of cracks in the members due to shrinkage Its dimensions are not decided from the diagonal tensile stress All listed here Large size of long beams carrying large shear force need not be adopted Removal of cracks in the members due to shrinkage Its dimensions are not decided from the diagonal tensile stress 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) 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
