Re: Wood Shearwall Blocking

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I would be very doubtful that such a connection could properly restrain the plywood panels against rotation. IMO the result would be, at best, more flexible--& likely much weaker. Furthermore, it is hard to see how this saves any construction cost if there is access to allow block installation. I'd say no. Unless he can provide test results on such an installation--fat chance.

I've got a project in construction and am utilizing wood sheathed

There are shearwalls with various nailing patterns, but all have been
designed as blocked.  The contractor has asked the question as to
whether they can substitute screwed light-gauge strapping for the wood
blocking.  I have heard of strapping being used as blocking in
light-gauge shearwalls, but I haven't seen light-gauge and wood being
mixed in this way.  Does anyone have any thoughts on this or a possible
reference to go by?
