Oregon pushes for wooden skyscrapers to revive timber industry

“Seems like a really stupid idea to build skyscrapers out of wood.”

Let's hope the engineers know what they are doing.

One thing about wood: at high temperatures, it keeps its strength longer that steel.

Steel beams, at high temperatures, lose strength rapidly and collapse. At that point, the building goes down immediately.

Yes, wood will eventually burn up. But a beam that has started to burn will hold its strength for some time. Char slows down the burning process.

So an eleven-story residential tower is perfectly safe, but the Delta Queen's interiors are not. I guess all woods may be equal, but some woods will be more equal than others.

“Oregon pushes for wooden skyscrapers to revive timber industry”

What?? Is sanity regaining a foothold in Oregon? The government has been owned by environazis there for ages. They killed the timber industry - I have a hard time believing this story.

Russian forest management?

“We are with state logging company. you live here? Leave now. We have nice apartment for you in Semipalatinsk. No, you misunderstand. not phrased as question. Leave now.”

Actually, my timber working (@40 yrs) husband said these beams are as good as steel....but he laughs at how wood in Oregon has been hated for @30 yrs....and suddenly wood is in...and hes about retirement ready

Might check with Chicago and San Francisco as to what can happen to a wooden city. Rome, for that matter. Some people never learn.

Termites? Wood bees?
These buildings would be easy to bug.

They’re treated

Soon California democrats will show up and protest her, blaming Trump for it.

And yet they can’t have a paper bag.

Cross-laminated timber (CLT) is a large-scale, prefabricated, solid engineered wood panel. Lightweight yet very strong, with superior acoustic, fire, seismic, and thermal performance, CLT is also fast and easy to install, generating almost no waste onsite. CLT offers design flexibility and low environmental impacts. For these reasons, cross-laminated timber is proving to be a highly advantageous alternative to conventional materials like concrete, masonry, or steel, especially in multi-family and commercial construction.

Your husband is correct.
Heavy timber is a better-safer structural building material than steel concerning fire. The char will go only an inch or better deep and insulate the interior. Timber is actually an exceptional building material for tall buildings. It is however, an engineered product.

Woods are different.

Balsa is ok for use in model, and some real, aircraft. But I would not want a baseball bat made of Balsa.

Neither would I want the aft main shaft strut bearings in a nuclear submarine, battleship, or destroyer made of Balsa. For that I would use the wood from Lignum Vitae.
