Brace Wall Panels & Alternate Brace Wall Panels.

The Feedback I received on some plans has the following comments:

Identify all Brace Wall Panels @ min 4' and Alternate Brace Wall Panels less
then 4'
min 2'8" w/ hold downs min 1800 psf capacity shall be located within 8" of
each corner.

BWP/ABWP - min 3/8" ply w/28 @ 6" O/C edge 12" O/C Field


I think I have an Idea of what they mean but not sure.

So I just label BWP if there is a wall @ a corner that is 4' or more and
ABWP if the wall from the corner is less the 4'

More or less depending on placement of window/door, etc?

Is this correct?

Thanks,

Your interpretation is essentially correct. You will also have to call out
the proper holdowns at the ABWP locations.

Take a look at the Code Book in effect for your local jurisdiction. I can't
believe you'd be submitting plans for approval without having that reference
at your fingertips.

I like to Live Dangerously (-;

I have the Residential Construction Code book put out by our County, though
its not really laid out in any reasonable fashion. No Index or anything.

The closest thing I found was a Softwall Brace Detail.

So the Hold downs are the Simpson PHD2, HD8A and HT22 that I want connected
to a Post or Double Stud?

I'm guessing I'd use one on each wall coming from the Corner and at the Next
Opening for Window/door?

Thanks for your Help!

You should be able to find everything you need to know in the section of
your code dealing with Lateral Design (wind and/or seismic). Sorry, but
other than that, a public AutoCAD newsgroup just isn't an appropriate place
for instruction in the details of building design, especially since code
requirements and interpretations vary with jurisdiction. The references you
mention sound like they're from the 1997 UBC, which has been superceded in
many jurisdictions. However, I'm sure if you ask, your local Building
Official will be happy to cite the exact Code section and paragraph for you
to study. The Simpson catalog will also give you a variety of solutions,
once you know what capacity holdowns you need.

Thank you for your input.

I think my book is a bit Old. I bought it about 4 Years ago. I'll see
about getting a new one. (-;

Thanks again.

I'd say that the two holdowns surrounding the opening in the right-hand
(east?) wall are redundant. Other than that the callouts are probably OK.
The only one who can say for sure, however, is your local Building Official.

Thanks for the Input!

I hopefully should be submitting the plans for a permit this week! Wish
me luck!

Thanks again!

I work for a lumber company where our main focus is designing and
fabricating trusses and wall panels. Within the last few months the issue of
wall bracing has taken a few different paths as far as types and locations
of bracing. The biggest change is the addition of engineered shear wall
panels for the short walls to either side of the garage door and for walls
over ten feet tall (this is all for residential BTW). We have been to almost
every meeting put on by the local building officials (we are in Ohio) and
also by Simpson Strongtie (they sell pre-fab shear panels) and what I can
tell you is that each and every lecture we have been to has had a different
way that they want to see things done.

Our biggest problem to date is trying to educate the building inspectors on
the correct ways to brace a wall line (according to the IRC).
