RE: temp steel

[Subject Prev][Subject Next][Thread Prev][Thread Next]
If wall is not tied at top to anything that would restrain shrinkage,
you could get by with just flexural reinforcing that direction, *but*
100' horizontal will cause humongous shrinkage stresses unless relieved
by contraction or expansion joints.  Even your #4@9" is *barely* over
the ACI Code minimum for Grade 60 reinforcing.
