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 (C - 1) mf + eE (1 - C) mf + eE (C - 1) mf - eE (1 - C) mf - eE (C - 1) mf + eE (1 - C) mf + eE (C - 1) mf - eE ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If Sb, is the average bond stress on a bar of diameter ‘d’ subjected to maximum stress ‘t’, the length of the embedment ‘l’ is given by l = dt/2Sb l = dt/Sb l = dt/4Sb l = dt/3Sb l = dt/2Sb l = dt/Sb l = dt/4Sb l = dt/3Sb ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design The load stress of a section can be reduced by Replacing smaller bars by greater number of greater bars Decreasing the lever arm Replacing larger bars by greater number of small bars Increasing the total perimeter of bars Replacing smaller bars by greater number of greater bars Decreasing the lever arm Replacing larger bars by greater number of small bars Increasing the total perimeter of bars ANSWER DOWNLOAD EXAMIANS APP
