[TowerTalk] Rebar Cage Question

[Dr M J DiGirolamo]

Phil,

  If you are planning to use a Ufer ground, the rebar MUST be welded.  There
is a different type of rebar that you must order.   Speak to the rebar
supplier (metal supplier) and they'll tell you what the number is.  I just
did one last year for a USTower 72' self standing tower.  It's a totally
different beast from regular rebar - the steel is much more refined.
Surprisingly, it wasn't but a tiny bit more expensive than regular rebar.
Be SURE ALL JOINTS are WELDED or the inspector will getcha!

   You can view photos of the rebar cage (as well as my entire project)

Phil... 

Welding on rebar is not the preferred method of construction, as it may
weaken the steel. Before I knew better, I tried this once and the welds
didn't hold well (and they were -- in theory anyway -- done by a
professional). Not saying it can't be done, but there are many who argue
against welding.

OK now we are getting to the question I have been wanting to ask. Can a
rebar cage work just as well if it is cut and welded together rather than
bent and wire tied? It is my plan but thought I might toss the idea out for
the critics.
