Stirrup Ranges

[vforvendett4]

What are the terms of the joint and overlapped joint shown in the appendix, in the beams? We already know the clarification zone, but what is the function of the other two?

The screenshot you added is for colon stirrups. Separate stirrup spacing can be given for 4 regions in the columns. In the beams, on the other hand, two boxes appear in the form of opening and wrapping.
