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: (C - 1) mf + eE (C - 1) mf - eE (1 - C) mf - eE (1 - C) mf + eE (C - 1) mf + eE (C - 1) mf - eE (1 - C) mf - eE (1 - C) mf + eE ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design ‘P’ is the pre-stressed force applied to the tendon of a rectangular pre-stressed beam whose area of cross section is ‘A’ and sectional modulus is ‘Z’. The maximum stress ‘f’ in the beam, subjected to a maximum bending moment ‘M’, is f = (P/'+ (Z/M) f = (A/P) + (M/Z) f = (P/A) + (M/6Z) f = (P/A) + (M/Z) f = (P/'+ (Z/M) f = (A/P) + (M/Z) f = (P/A) + (M/6Z) f = (P/A) + (M/Z) ANSWER DOWNLOAD EXAMIANS APP
