Development Length Parameters

The Development Length for a Hooked Bar formula is defined with fy= 60 ksi (413.7MPa), where db is the bar diameter, in (mm), and is the 28-day compressive strength of the concrete, lb/in2 (MPa).

Why are Hooks provided in reinforcement?

Hooks are provided for to resist seismic movement. To prevent concrete from splitting outward. It prevent slippage of steel from the concrete.
