Rebar Development Length Calculator to ACI 318

02/12/2020  Development of Standard Hooks in Tension. Deformed bars can be effectively anchored in concrete by curtailing the end of the rebar with a 90° or 180° standard hook allowing the rebar to develop its full strength in tension. ACI 318-14 specifies minimum geometry for standard hooks.

Development Length in Reinforcing Bars The Structural World

16/03/2018  Development length of standard hooks in tension (R25.4.3) Study of failures of hooked bars indicates that splitting of the concrete cover in the plane of the hook is the primary cause of failure and that splitting originates at the inside of the hook where local stress concentration is very high. Thus, hook development is a direct function of bar diameter db, which governs the magnitude of ...
