Simple response to Query 1. Why & Yes

Simple response to Query 2 Yes if done correctly.


Sorry Dan but timber framed structures either have to satisfy
"convention construction" prescriptive "design", be designed per some
sort of code or be engineered. In order to do these things one must
know the operational environment of the structure. Changing from
convention construction to alternative materials & construction
methods requires evaluating whether the substitute meets / exceeds
that of the original.

"the devil is in the details"

>>>>I thought the questions would be extremely simple for people that build with
wood, but perhaps I was wrong. <<<<<<

If the 2x6 brace is already in place, why the question about the metal
banding?

If the walls are 16' high, why is the blocking at 5' o/c?

Dan:

I would not even venture to guess at the answers to these questions in a
post to a newsgroup. There may be issues unrelated to the structural
design (such as fire blocking) that are part of the question and part of
the problem.

You said the project is in NE Washington State. AS I'm sure you know,
Washington uses IBC2003 for any non-residential structure. Most
jurisdictions in Washington State will require engineering calculations
for any changes to the structural system.

And yes, I could do this work, but it would be 6-8 weeks before I could
pick it up.

Bob,
Therein lies the gist of my query. According to the property owner, the only
inspection required is septic and power. Building permit comes from the
county with no plan review, according to the owner and I've never known this
guy to lie. Seemed strange to me but.........Building is in the county.

The owner asked for a mix of design. He didn't want a full blown wood framed
wall as one usually would. He wanted to eliminate the fire blocking,
although the walls are 16' high, because the interior is not covered
(sheetrock/OSB, etc.) in any way. It would be open like a pole building on
the interior with faced insulation between the studs.

I asked if the wood diagonal bracing could be replaced with properly
fastened steel banding to provide shear loads because the owner asked. Much
like diagonal cabling or diagonal brace rods in a PEB. The exterior of the
building will be gauge metal sheets. Hence my question of the 1x4's with the
wall sheets as a part of the shear. The 1x4's would act as sheeting girts
like a PEB or pole building. Owner has no plans to install OSB or like
sheathing to the exterior walls. Owners comment was if he can do it
differently and faster and cheaper but still be solid as hell and meet or
surpass any codes that might come up, why not.

I would have IF I had a place to post them. I suppose there are places but
I've never been there. It's my understanding it's not within etiquette to
include them as attachments within the NG. But as I stated, I can send them
'as type' if someone asks.

26 years in construction in almost every field but wood. Some formwork but
darn little. Completly remodeled/reframed/rewired/replumed (including newly
framed doors/windows/etc) my last house with no mistakes in the city &
passed all inspections. However, I didn't feel that made me qualified to
answer the questions I raised. Steel, yes, wood, no! At this juncture Rico,
we can't even seem to get past this wall, let alone other details.

The owner is looking at different methods that will meet/exceed any current
codes, albeit he states there's no plan review, yet can be done faster &
cheaper. As in why install fire blocking if the interior is open? Why cut
diagonal 2x6's into the face for shear if you can use properly attached
metal strapping with the addition of the exterior 1x4's with metal siding?
When the owner started asking me why not, it made me wonder as well.

Dan-

>>>>The owner is looking at different methods that will meet/exceed any current
codes<<<<<<

if he's looking to meet or exceed a code....we kinda have to know
which one OR at the very least where the building is going to be;
snow? wind? seismic?

desired performance level? life safety only? moderate damage from a
50 year event? minimal damage? fully elastic?

>>>>>>As in why install fire blocking if the interior is open? <<<<<

I must have missed that in the OP, nothing on the interior?

>>>Why cut diagonal 2x6's into the face for shear if you can use properly
attached
metal strapping with the addition of the exterior <<<,,

Metal strapping is an alternative to a let-in brace system, not much
of an alternative IMO

I've tested let-in braces (1x4 or 1x6) in a 2x6 wall.....they're
amazingly strong, IMO straps are a crappy cheap alternative. Who
came up with a 2x6 let-in brace?

>>>>>exterior 1x4's with metal siding?<<<<<<

Is the metal siding, siding or structural sheathing? What are the
surfaced mounted 1x4's supposed to accomplish? How thick is the steel
"sheeting"; flat or corrugated / ridged? fastener style, size &
spacing?

How is metal supposed to work as structural sheathing if it's held off
the framing (studs) by the surface mounted 1x4's ? what is the
estimated demand on the 1x4 when it acts as "shear transfer
blocking"? Is 1x4 adequate to provide continuity of load path for the
metal sheathing? I doubt it.

In order to design something like this this (& not use a code,
convention construction or a prescriptive design methodology) you have
bounce back & forth between "capacity" & "demand" and constantly
thinking about load path .....

Oh but not foundation or any of the other "off limits" topics from the
OP.

What's gonna hold this thing together when the wind sucks the roof off
as a single unit.....better not discuss any hurricane ties.

Just because the process might appear to be simple (it ain't) or the
process appears easy (it is, IF you know what you're doing; & know
what to consider, what to ignore......it's called experience)

Seismic in Texas...probably not a huge factor, wind in WA....maybe
something to consider
Snow is Orange County, CA not a concern snow in WA....I don't
know, I'd have to check.....elevation

Snow in SoCal not a problem....oops! I forgot to tell you, the
building site is at 6000 ft! & the roof slope is only 4/12! Got me a
cheap set of plans off the internet.

cheers
Bob

btw construction ain't design & design ain't construction......but
both are required to get the job done.

The best jobs are gotten when each part considers the other.........

Nope! Well, insulation between the studs.

Now here's the question, why can't metal banding/strapping work, =
properly applied, as well as cut in diagonal bracing for shear? Whether =
it's interior/exterior or both?

Corrugated wall sheathing. 1.5" highs. Ribbed panels as in a PEB.

Therein was a purpose for my query. I stated my expertise relative to =
wood is nil.=20

yep!

Bob, you know as well as I do, there are extraneous answers and queries =
unrelated to a post that detour from the OP. I just wanted to avoid the =
extraneous and subjctive stuff. Albeit it seemed to irritate some....

> What's gonna hold this thing together when the wind sucks the roof off
> as a single unit.....better not discuss any hurricane ties.

Here and again, we're not at that point in the design, henceforth, =
irrelevant. I'm just asking about a DCN for a wall.
=20

Been there, done that! But my experience is primarily steel. Which is =
why I asked about the faced 1x4 for shear, with the metal wall =
sheathing. A PEB is a freak until the wall sheets are applied to get =
shear.

> Seismic in Texas...probably not a huge factor, wind in WA....maybe
> something to consider

No wind in 60 years. Per owners father that lives there.

> Snow is Orange County, CA not a concern snow in WA....I don't

=20
Elev. unk. <3000' Snow loads are a different consideration but will be =
addressed for enginereed trusses and purlins.

AMEN to that. Can you plz fwd that to our engineers and fabricators? =
I've got over 300 manhours in rework and some of it is from going to =
hell to get it done.
