RCC Structures Design Pick up the assumption for the design of a pre-stressed concrete member from the following: A transverse plane section remains a plane after bending All listed here Variation of stress in reinforcement due to changes in external loading is negligible During deformation limits, Hook's law is equally applicable to concrete as well as to steel A transverse plane section remains a plane after bending All listed here Variation of stress in reinforcement due to changes in external loading is negligible During deformation limits, Hook's law is equally applicable to concrete as well as to steel ANSWER DOWNLOAD EXAMIANS APP
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
