RCC Structures Design In a pre-stressed beam carrying an external load W with a bent tendon is having angle of inclination ? and pre-stressed load P. The net downward load at the centre is W - 2P sin θ W - 2P cos θ W - P sin θ W - P cos θ W - 2P sin θ W - 2P cos θ W - P sin θ W - P cos θ 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 (t + c)/n = (d + n)/n mc/t = (d - n)/t (m + c)/t = n/(d + n) mc/t = n/(d - n) (t + c)/n = (d + n)/n mc/t = (d - n)/t (m + c)/t = n/(d + n) mc/t = n/(d - n) ANSWER DOWNLOAD EXAMIANS APP
