What is the meaning of (DEAD END) at prestressed slabs?

Dead end is the end of the tendon which is anchored in the concrete beam or slab whilst stressing takes place from the opposite (live) end.

Dead ends may be of a swaged, onion or H-type.

In strand set-ups where ends will protrude above the face of the concrete element and may create a hazard, they should be boxed or barricaded to prevent injury.
