About Basement Floor Perimeter Curtain Distributions

Hello, in TBDY 2018, no separate reinforcement definition was made for basement curtains. It was absolutely necessary to insert the horizontal reinforcements into the curtain cap, because in practice it was often problematic to make miter+hooks as in DBYBHY 2007, and this was not followed in most construction sites, especially in curtain combinations. As a matter of fact, the horizontal reinforcement of the curtain is entrusted to the concrete as much as you know. In the new application, if the anchorage length is not sufficient, a square must be made in the head, which is not possible. Therefore, I think it is important to choose the curtain cap length long enough for the anchorage length of the horizontal reinforcement.
Thank you Erhan for your reply. Thank you for the other information you have given to the forum before... In some basement curtains, headboards may not be formed, for example, corner turns or places that protrude beyond the column contours. In some places, we can put columns on the shear beam junctions, the columns here are as if the elements inside the curtain, I think cranking here can be annoying in terms of application. Let's choose the best from the heart. I think a separate explanation could be made for the basement floor curtains, but it's not so important, good work everyone...
Hello, You're welcome, I'm trying to help as much as I know. I forgot to mention in my previous message: The importance of horizontal reinforcement in basement curtains is not like in main carrier curtains. For this reason, I think that it is not a problem to make old-style exteriors. Of course, this is my personal opinion. Horizontal reinforcement drawings are generally not drawn correctly in the intersection area of the shears that connect to each other at different angles than 90 degrees; That's why I add colons to these places so that they are drawn properly. I am not creating a column where each beam is provided to the curtain. However, I add a column in the region where the beams with high load and large span are stuck in the curtain. By increasing both the stirrup tightening and the longitudinal reinforcement, the ductility increases in that region.
