Concrete Technology and Design of Concrete Structures
The centroid of compressive force, from the extreme compression fiber, in limit state design lies at a distance of (where xu is the depth of neutral axis at the limit state of collapse)
is independant of both ast and acbc where d is the effective depth, ast is per-missible stress in steel in tension and ocbc is permissible stress in concrete in bending compression.
