Six Stories In Wood

reveivl

Heard on the radio today that the BC code is changing to allow six stories of wood framing to replace the previous limit of four. Citing density requirements and modern engineered wood products.

I don't do that sort of thing, but kinda interesting. Wonder what some of the caveats are. The first few engineers are gonna be sweating a bit.

We have done 5. I will say there is a lot of wood in the first floor.

i was also involved in framing a 5 story apartment, however the first story was basically all steel


isn't that intresting....that is alot of lumber....alot

The amount of wood required (and extra labor cost) to make this safe wouldn't be sufficient to me, there is no way I would build 6 stories in wood.

I agree. Fire, mold, insects. There are better materials and i would think for the same money.

We are working on a complex now in MD thats five on one side and four on the other with lofts on top of each.
Bottom floor the studs are in packs of 5 and each floor we go up they eliminate 1 stud. There is a small amount of structural steel but not much.

I wouldn't want to live on the 6 floor.....lol I wouldn't want to live on the ground floor either.

Most I've ever seen was 5 floors, and even that didn't seem very practical. The construction cost may be less, but I would imagine maintenance costs would be way up.

I framed this one 2 years ago in 130 mph wind load zone, Ocean Shores, WA

5 stories...all wood. The roof was a hybrid...the easy stuff on the left was trusses....the complex stuff was stick framed.

It doesn't seem so ominous when you see a picture of it. We did a 5 story but it had steel columns and steel flitch plates next to the engineer wood beams.

anyone ever been to the Old Faithful Inn? That is a wicked building. I know it's not exactly what is being discussed here, but it is a wood structure. Can't find how many stories it is, but I found it's 65 feet high.

I personally think this is no good! We can calc. shear, tension,and compression in a steel and concrete sturcture. Your talking about 60 feet in height. The pure wind shear and movement are not easily calced in a wood structure, you have to trust simpson and the wood gods calc's. I don't as they seem to have thier own secret formula's for doing things? When wood moves (and it will on something this tall) the ammount of stress on what is holding it together(nails) would be to much for einstien to figure out. Try doing a section modulus on a wood micro-lam (using thier span for spec'ed beams nothing works? It's just my opinion, but as a structural engineer, turned framer this is a no-no!!

I remember that place very well! the interior is even more amazing. But, since each floor gradually becomes smaller and consists of less mass, wouldn't that be more feasible then lets say a common 21st century apartment/condo block, where each level has the same live and dead loadings?
