clamping length

[damlatpz]

Hello, I have a problem about the static project; Minimum Reinforcement Overlay Length, which I sent by taking a screenshot, is marked 50 fi. At the same time, should the Min l box be checked as per the regulation? 9.1.2 on TS500. The places that say location1 location2 in the th section frankly confused me. I would be very happy if you could comment.
