Concrete Technology and Design of Concrete Structures If the depth of neutral axis for a singly reinforced rectangular section is represented by kd in working stress design, then the value of k for balanced section depends on aCbC only depends on both crst and acbc depends on as, only 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. depends on aCbC only depends on both crst and acbc depends on as, only 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.
