Concrete Technology and Design of Concrete Structures
Examine the following statements : i) Factor of safety for steel should be based on its yield stress, ii) Factor of safety for steel should be based on its ultimate stress, iii) Factor of safety for concrete should be based on its yield stress, iv) Factor of safety for concrete should be based on its ultimate stress. The correct statements are
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.
