Using steel chains as concrete reinforcement??

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Hi,
I'm working on a job in which the engineer is using a novel way to reinforce CMU walls. He's using steel chains instead of rebar, inserted from the top and then full grouted with 4000psi concrete. I guess he's been asked to justify the process and so he's come to us to do an evaluation. I was wondering if anyone had come across such a situation before and could advice us about the viability of such a process. Just from first glance, I feel that using chains as concrete reinforcement would lead to local stress concentrations that could cause the chain to break or yield locally. Perhaps it might be ok to use these chains at a lower strength value than what they're rated for.
Any advice would be greatly appreciated.
Thanks
ibrahim
