Concrete Technology and Design of Concrete Structures The critical section for finding maximum bending moment for footing under masonry wall is located at the middle of the wall at a distance equal to effective depth of footing from the edge of the wall at the edge of the wall halfway between the middle and edge of the wall at the middle of the wall at a distance equal to effective depth of footing from the edge of the wall at the edge of the wall halfway between the middle and edge of the wall ANSWER DOWNLOAD EXAMIANS APP
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 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 as, only depends on both crst and acbc 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 as, only depends on both crst and acbc ANSWER DOWNLOAD EXAMIANS APP
