Re: Plywood rigid diaphragms

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I was at the seminar as well. The "definition" of a rigid diaphragm language
has been in the code since 1994, I believe. I too have never designed a
plywood diaphragm, wood framed building as a rigid diaphragm. The speaker
was saying that this language is going to be a big hit for lawsuits when the
statute of limitations get near. Frankly, I think it would benefit the
profession if this language was revisited and revised.
