FW: Bracing for Nail-Plate Wood Trusses

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Dr. Woeste's graduate student published an article in the Nov./Dec. 2002
Building Standards Magazine (ICBO's magazine) on "Checking T-Brace Capacity
on Wood Truss Webs".  I have been unable to locate an electronic version of
this article, but have a hard copy in front of me.  One can contact ICBO for
a copy of the article.  I believe there is a nominal fee associated with the
request.  The article is NOT posted on the APA website.  Sorry about that,
but there are probably copyright issues.

HTH,

Kris,

First: this was the only time I saw your message

Second: Very boring ... but for some reason I read it all and chose to
reply :>

Third: There are some downloadable papers from Dr. Woeste of Virginia
Tech on this topic. I think you can get them at APA's website.

I apologize for re-sending this, but I haven't seen any responses; I
don't
know if this is because no-one saw it the first time, or because
everyone
else is bored to tears by the topic:
...........
I know this is an issue that was discussed several years ago, but I do
not
know if a consensus (or an accord) has ever been reached.

The Plated Truss Institute still insists that the EOR should be the one
to
design the bracing for the web members, along with the connection of the
bracing to the web members and the connection of the bracing to the
structure.  What a shift of liability!

I, of course, continue to believe that this ought to be dealt with by
the
truss manufacturer or designer, since it something that cannot even
remotely
be known by the EOR until after shop drawings are received.  Their
handbook
even acknowledges that the "building designer" might be the home-owner
or
contractor - then goes on to say that they should perform this
engineering
design function.

The local building department just realized that this is not being done
on
most of the buildings they see, so they want to see an engineer design
the
web bracing for each truss roof that is specified by an engineer (I
don't
know what they are doing for "house-designer" projects).

Is anyone aware if there has been any further action on this issue?  Or
is
everyone but me just "buckling" under and doing the design?  How many
were
not even aware that there was an issue here?
