Can someone explain anchorage length vs development length in beam-column connections? I’ve been trying to visualize where each one starts and ends.

From what I understand, the development length starts from the face of the column/beam joint up to the bend of the bar. Then the hooked part after the bend is considered the anchorage length.

So in a 90° hook detail, is the curved + tail portion already part of the required development length? Or is anchorage length separate from Ld?
