RCC Structures Design If C is creep coefficient, f is original pre-stress in concrete, m is modular ratio, E is Young's modulus of steel and e is shrinkage strain, the combined effect of creep and shrinkage is: (1 - C) mf + eE (1 - C) mf - eE (C - 1) mf + eE (C - 1) mf - eE (1 - C) mf + eE (1 - C) mf - eE (C - 1) mf + eE (C - 1) mf - eE ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design With usual notations the depth of the neutral axis of a balanced section, is given by t/mc = (d + n)/n mc/t = (d - n)/n t/mc = (d - n)/n mc/t = n/(d - n) t/mc = (d + n)/n mc/t = (d - n)/n t/mc = (d - n)/n mc/t = n/(d - n) ANSWER DOWNLOAD EXAMIANS APP
