for relatively large spacing of primary
layers (in our case, every three courses of
stacked blocks) as well as use of slightly
weaker reinforcement. Consequently,
without speculative consideration of savings
from avoiding failure, it is believed
that the added net cost of intermediate
layers material to the overall cost of project
is small, perhaps in the order of 1%
to 2%. The alternative solution of using
closely spaced reinforcement is excellent,
as it has been performing well; however,
it requires more reinforcement than the
case with secondary reinforcement.
Conclusions
It is demonstrated that using intermediate
reinforcement layers may alleviate
connection loads as well as reduce loads
carried by primary reinforcements.
This may be important when a slope is
constructed over the wall resulting in
improved wall performance. Also, it is
shown that very weak and short reinforcement
may enhance the stability of
such a slope, thus reducing likelihood
of such slope failure, which may damage
the upper portion of the SRW facing.
A rational and robust design approach
is used to render the required values of
reinforcement and connection loads.
