Hi everyone. There was a post tensioned cable failure on a post tensioned slab in a residential building. The cable was sticking out and noticeable. A piece of concrete stucco shot out like a projectile motion after the cable snapped. I couldn’t find the anchor plate around the area. I am not sure if the builder didn’t install an anchor plate during construction or what. I have few question regarding this issue.
- Do anchor plates required for all post tensioned cables? What will happen if I don’t use an anchor plate?
- If the cable snaps, what is the difference between having an anchor plate and without it, eg. damage to the slab, cable stress allowed, etc?
Thank you very much.
