Anti--burst reo location tolerance?
Anti--burst reo location tolerance?
(OP)
Hi,
I was looking at a stressed slab today. I noticed the anti-burst helices were tied hard against the tendons.
See this image for the type of construction practice I am talking about.

From a theoretical strut and tie perspective this wouldn't work as well, but I'm not a PT guy, and I wasn't there to sign off on it.
I commented on it to the PT foreman, but his attitude was along the lines of "this is how we do it".
Is it standard practice? Does it work ok?

AND, your photo does not show any plastic/steel 'onion' spacer plates at the 'bulb' ends. These are required to ensure that the strand ends are not displaced during concreting etc.

I'm just curious how wide spread this practice is, and to what degree it's considered acceptable at large. Clearly these guys have been getting away with it, and their engineers are apparantly ok with it.
The photo I linked to isn't my photo, it's just a photo I found online illustrating what I meant. I found other photos online too, showing similar thing, so clearly this practice is out there.
