Dom;
One possible problem might be corrosion of the wire which is
in contact with the ground.
Also, tensioned cable or wire tends to concentrate the stresses
on a very small bearing area which could result in crushing
unless bearing plates are provided .There's also the issue
of uneven distribution of the stresses. ie One would get "bellies"
in the region of the ties with humps in between unless the top
plate is very robust (ie material intensive).
I think that if one wants to use steel tensioning members, then
using the lath as the tensioning element makes a great deal of
sense as the load is more uniformly distributed along the
length of the wall components .
One idea that was discussed many moons ago was the notion
of using reclaimed automobile seatbelts (woven polyester)
(see "Kiwi Ties" in the archives) which could be laid on the
earth prior to the pour. Plenty strong without the corrosion
problems, no potentional for getting poked in the eye (or
other)
by a loose cut end and being recycled, a nice shade of Green .
