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 (m + c)/t = n/(d + n) (t + c)/n = (d + n)/n mc/t = n/(d - n) mc/t = (d - n)/t (m + c)/t = n/(d + n) (t + c)/n = (d + n)/n mc/t = n/(d - n) mc/t = (d - n)/t ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If R and T are rise and tread of a stair spanning horizontally, the steps are supported by a wall on one side and by a stringer beam on the other side, the steps are designed as beams of width R - T √(R² + T²) R + T T - R R - T √(R² + T²) R + T T - R ANSWER DOWNLOAD EXAMIANS APP
