What are embedded length and development length?

Question

Accepted Answer

Embedded length is the length of reinforcement bar embedded in concrete, while development length is the length required for the bar to transfer its load to the concrete.

Embedded length is the portion of the reinforcement bar that is embedded in concrete to provide structural support.
Development length is the length of reinforcement required for the bar to transfer its load to the concrete without slippage.
Embedded length is typically specified in building codes and design standards to ensure structural integrity.
Development length is calculated based on factors such as bar diameter, concrete strength, and bond strength between the bar and concrete.
For example, in a reinforced concrete beam, the embedded length of the rebar at the support region is crucial for resisting bending forces, while the development length along the span helps prevent shear failure.

Accepted Answer

Embedment length — the length of embedded reinforcement provided beyond a critical section.
 Development length — the length of embedded reinforcement required to develop the design strength of reinforcement.
