Anchorage Length: Basic vs Equivalent

[dss975599]

Homework Statement

Guys , what is the difference between the basic and equivalent anchorage length ?
For the basic anchorage length , it is measured for the whole bend as in the figure a ..
For the b , for the equivalent anchorage length , why it's measured from one side only ? ( longer side)

The Attempt at a Solution

I think for figure b , it's wrong ... It 's shold be measured for the whole L shape bend like figure a . Correct me if i am wrong . Thanks .

Maybe tight bends, beyond 90° place the hook part of the bar in compression, not tension.
Refer to; 8.4.1
(3) Bends and hooks do not contribute to compression anchorages.

Equivalent anchorage length is the length of the steel reinforcement that will be engaged through tensile strains in reinforced concrete.

Basic anchorage length is the equivalent anchorage length + the bent portion of the steel. The bent portion of the steel is not considered to resist any tensile strains/stresses and is simply provided to prevent the steel bars from slipping out of the reinforced concrete.
