We are providing
braces to an existing CMU wall with skip grouting. We will need to provide
anchors at grouted AND at ungrouted conditions. The bracing will occur in two
stages. First, temporary bracing will be installed to be followed by permanent
bracing. The only anchors that I can find that can be used in ungrouted cells
like the Simpson epoxy tie anchor, are not available to resist seismic forces.
The ICC Evaluation Report says only that they can be used to resist dead, live
and wind loadings. The only thing I can find is the Titen screw that is only
good for 200# tension. Way too low for our
Is anyone aware of an
anchor product for use in an ungrouted CMU cell that can be used to resist
