This message is mainly intended for John Rose of APA but I am interested in
hearing from anyone else who might have had some experience with this.
There is an old APA report dated 2/5/85 that describes a procedure for
stapling 24 or 26 gage sheet metal to an unblocked plywood diaphragm. The
conclusion is that strength of the diaphragm can be increased to the
equivalent of a blocked diaphragm by following this procedure.
In our case, we have proposal for applying this procedure to a 1x straight
sheathing in a URM building. The questions are:
1- Is this report still valid?
2- Can it be extrapolated to 1x sheeting with the expectation of
achieving the same capacity as plywood?
Thanks for any input
