wood-skyscrapers How to build a skyscraper out of wood

Building skyscrapers out of wood: It sounds bizarre, unsafe, maybe even a bit twee. But it could actually be the future of construction. I can say it should be just as relevant in the discussion of what material to use. Snapp is the design principal guiding the firm's River Beech Tower project, an foot residential skyscraper that would be built almost entirely out of wood.

The tower wood skyscrapers designed in wood skyscrapers with a master plan the firm was awarded to develop an wood skyscrapers in Chicago's downtown, on the east shore of the river and just west of Grant Park.

Cambridge University's Natural Material Innovation project then came to them with the notion of doing a wooden skyscraper. Woodd idea was they would pick a real-world site and then develop the building from the ground up: As the architects fleshed out the project, that would give the Cambridge group specific structures, practices, and so skyscrapfrs to test out 20 Easy Woodworking Techniques Review in the lab.

Let's have a real site. Artist's rendering of the River Beech Tower project. Granted, River Beech Tower remains purely conceptual — a collection of designs and models, with no actual plans yet to build it. But the point of the project was to prove the idea could work.

Nor is it the only such effort. Similar plans are underway in London, Stockholm, and other cities. Eighteen-story buildings made of timber already exist in Vancouver and Minneapolis, while other structures have popped up in Norway and New Zealand. In fact, the city's great fire of was one of several disasters wood skyscrapers helped push modern architecture away from wood and towards the steel and concrete that dominate construction today.

Part of that legacy is Chicago's architecturally iconic Wrigley Buildingwhich houses the offices where Snapp and his colleagues did much of their work on wood skyscrapers River Beech Tower project. It's one of many efforts around the world to take history full circle and return timber wood skyscrapers a place of prominence in architecture.

For one thing, wood is lighter and more flexible than steel or concrete. A wooden skyscraper will have more give in an earthquake, for instance. The lighter weight also opens up opportunities for cost saving throughout the construction process.

Wood is an excellent insulator, which would save the building's owners and residents on heating wood skyscrapers cooling costs. On the flip side, wood can sway too much, particularly in the wind — a major issue for taller buildings. For wood skyscrapers River Beech Tower project, Snapp and his colleagues actually solved this problem by constructing the whole building out of skyscarpers and diamond shapes.

A triangle is a much more structurally sturdy form than a rectangle, so taking a more flexible material wood skyscrapers wood and building triangles out skyscra;ers it wood skyscrapers a structure that holds up well under forces coming at it from all sides. It also lent the project its interesting "honeycomb" aesthetic.

Key connection points in the building would be reinforced with steel encased in concrete, and glass would be used in windows along with some other exterior materials.

Beyond that, the skyscraper wood skyscrapers be basically all wood. Solving the flexibility vs. The engineers determined the skyscraprrs bottom third of the building would have to be a solid wood block to give the structure enough stability.

So they redesigned the building as essentially two skyscrapers conjoined by a central atrium. That allowed them to spread the base of the wood skyscrapers wide enough to get the necessary structural stability.

It also gave them a big open space woood up the core of the building, which wood skyscrapers up all sorts of aesthetic and interior design possibilities. Another interesting aspect of wood is that it's easier to wood skyscrapers with than steel wood skyscrapers concrete.

Concrete has to be poured woov a preset wood skyscrapers, then allowed wood skyscrapers time — wood days or weeks — to dry. Steel has to be melted and molded into skyscrxpers necessary shapes. Wood, however, can simply be cut. Computers and modern technology now allow for factory wood skyscrapers that can cut timber into all sorts of desired shapes quickly and in large quantities.

That fact allowed the River Beech Tower team to get creative about the construction process as well as the design.

They came up with a plan where the building would be constructed out of standardized modules, all prefabricated at a nearby factory, then shipped to the construction site. This modular approach is not unheard of in standard construction, but it's still relatively new, and the use of wood allowed the team to wood skyscrapers full advantage of it.

It's a strategy that can save you a lot of time. And building the modules under factory settings provides for more quality control than building the whole skyscraper on site from the skysdrapers up. How far this practice could spread depends on the circumstances of each building — having Lake Michigan right next to Chicago was a big help for shipping plans — but it certainly has possibilities.

Of course, any talk wood skyscrapers building skyscrapers out of wood is immediately going to raise concerns about fires. Remember the aforementioned Great Chicago Fire of ? But wooden beams can be covered with fire-proof coatings, wood skyscrapers as steel beams are. More importantly, the wooden beams created with modern processes are so big and solid that it actually takes enormously high temperatures to set wood skyscrapers on wood skyscrapers — below those temperatures, the surface of the beam simply chars, while the beam itself maintains its structural integrity.

Finally, it's also worth mentioning that a world where we built a lot more skyscrapers out of wood skyscrappers almost certainly be a more environmentally friendly place. Obviously, there are aspects of construction that will emit CO2 no matter what material you use. Wood skyscrapers steel and concrete also have carbon emissions intrinsic to that material: Sixty percent of concrete's emissions, for instance, come from the chemical reaction to make the concrete.

Replacing a lot of steel and concrete construction with wood could save us a lot of CO2 output. On top of that, timber is a cash crop, just like corn or potatoes. If wood for it goes up, the wood skyscrapers incentive to plant more trees increases too. If wooden construction became common, you'd certainly need regulatory oversight to make sure the timber came from cash crop planting and not from cutting down pre-existing wood skyscrapers. But planting more trees is an wood skyscrapers idea for fighting climate change.

Mainly time, experience, and acceptance. Architects and engineers are only just beginning to realize the possibilities of bringing wood back into the equation, now that engineering technology has advanced. Governments and construction companies still need to get used to the idea.

And building codes need to change: Right now the most widely used codes limit wooden construction to around 20 stories.

The field of wooden skyscrapers is young. But like the trees it relies upon, it may yet grow into something remarkable. How to build a skyscraper out of wood.

The River Beech Tower is a conceptual wooden skyscraper that's 80 stories tall. When Chicago’s John Hancock Center was built in , it required 5 million pounds of aluminum, roughly enough metal. Forget steel and concrete — wood is the latest go-to material for building skyscrapers. The renewable resource has high potential. "The world's tallest wooden house!" reads a huge poster on the. 9 hours ago · Since the dawn of the skyscraper age, cement, concrete and steel have molded our vertical urban realms. But the environmental consequences of these materials has led some in the construction industry back to wood, a material that’s more sustainable and, with each technological leap, an increasingly viable option for large-scale projects.
