Plastic hinging
Plastic hinging
(OP)
Hi guys!
As I google the definition of plastic hinging one of the answer states that, "a condition where a member can bend further but there will be no increase in resisting moment".
I would like to ask what contributes to this mechaninsm (strain hardening maybe).
I have used ACI chapter 21 requirements for design of special moment resisting frame and i know it considers the action of plastic hinging but to grasp a better concept of design I would like to know more about plastic hinging and its effect on the structure.
Thank!

RE: Plastic hinging
I have little insight into plastic hinging in concrete structures, but it would involve yielding of the reinforcement.
RE: Plastic hinging
I see. Thanks for clarifying that plastic hinging is not a result of strain hardening because such hardening occurs beyond ultimate strength of the material far beyond its yield point, Im a correct?
I beleive plastic hinging is really dependent on yeilding of reinforcement. hokie66, your little insight wil be a great help to me.
If you could post any material for further reading it will be much appreciated.
