RE: bearing on cmu wall

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Ahhhhh, but ACI 530 basically requires "special inspection" or their
approximation there of.  <grin>  ACI 530 does not allow an option of no
"special inspection" and then reducing stresses by 1/2.

And just think of the more fun that those of us non-UBCers will have when
ACI 530 finally includes/switches to an USD method!!
