Metal studs and trusses for wind mitigation

[Steve E. Hord]

Did a house yesterday that was a "kit House". 100% metal walls, rafters, etc. My question lies in regards to the wind mitigation and the truss to wall connection, how should this be rated? Anyone else ran across this and had any luck? The owner/builder states the home is rated for 150MPH wind load, which I am waiting on certification papers to verify.

I to would love to know what you all think. Steve since it is a kit house maybe the manufacturer or the folks who sold it would have the drawings and engineering info. They then should have the NOA's and such.

[Jeffrey R. Jonas]

Don't know about down there, but up here it's nothing but a fancy manufactured home, and would pay through the nose for insurance. One little "puff" and it's G-O-N-E !!!

I am waiting to see what type of engineering documentation it has with it. Apparently he could get different kits with different wind loads. It certainly is not the norm. And as with all home owner built homes... it scares me.

Where is this? There are several of these homes just north of Hillsborough blvd near the turnpike.

I would guess you would have to get the specs from the build and then.......it will be up to the underwriter.

Looks to me like it meets the definition of a clip to me..

Secured to truss/rafter with a minimum of three (3) nails, and
Attached to the wall top plate of the wall framing, or embedded in the bond beam, with less than a ½" gap from the blocking or truss/rafter and blocked no more than 1.5” of the truss/rafter, and free of visible severe corrosion.

B. Clips
Metal connectors that do not wrap over the top of the truss/rafter, or...

Only issue might be the word "nails". Would have to prove whatever is attaching those is equivalent the the strength of a nail...

Provide the specs, fill out the form per the specs, it's any system that provides the required uplift, if COed by the AHJ and you provide the required specs and observed the installation per specs you should be good to go.

For the roof to wall system I would think this could be marked as structural. It looks like the "roof to wall" system is bolted. Or it could be marked as "other"

For the deck fasteners they should be screws no?

[Pete Campbell]

Just WTF will it take to get new ppl to set up with their info., esp. LOCATION?!?

[Dave L. Walsh]

You tell me, not that I am "new". I have checked and my info is all there on the profile page but does not show up on the MB. I'd love to know.
