  • Explore the viability of wooden skyscrapers, and see how cross-laminated timber (CLT) helps make these once impossible structures possible.
    --
    Towering 85 meters above the Norwegian countryside, Mjøstårnet is the world’s tallest wooden building, made almost entirely from the trees of neighboring forests. But as recently as the end of the 20th century, engineers thought it was impossible to build a wooden building over 6 stories tall. So how do wooden structures like this compare to steel and concrete skyscrapers? Stefan Al investigates.
    Lesson by Stefan Al, directed by Franz Palomares.

    There are a few different issues with timber. Wood "lives", which means it expands and contracts under different environmental conditions. Timber is also so lightweight, that it could create issues in high rise construction regarding vibrations. Also, when timber is loaded for a long time, it gets issues regarding creep. Furthermore, the glue in GluLam is far from environmentally friendly. Lastly, detailing is very difficult, because as mentioned in the video, timber is very weak in any other direction than longitudinal. This means that a bolt or nail could easily fail when it is loaded in the "wrong" direction. Now, this doesn't mean that there is no hope or reason to build high rise buildings in timber, but the industry is still a little bit in its infancy.

    • @rossjubic8567
      @rossjubic8567 2 ปีที่แล้ว +3

      Yeah this video is very misleading all around. Don't get me wrong, glulams are great if you want some architecturally exposed beams or your building on an existing wood construction and can't use steel, but you really need a unique case in order to go out of your way to specify it from standard cut lumber and other building materials.

    • @mreagle8770
      @mreagle8770 2 ปีที่แล้ว +3

      All materials expand and contract under different environmental conditions, accounting for these is part of the design process. All materials creep, accounting for this is also part of the design process. And you cant really compare CLT and glulam to "timber". These are engineered woods, their properties aren't the same as a lone plank of wood. For directional strength, CLT addresses that issue by having the timber planks arranged in both directions, and you would usually use glulam in the longitudinal direction it was orientated, though it can still perform well in other directions if its designed for it. Ultimately, there is no need to make a purely "timber" building. Use an optimal combination of timber (engineered), steel and concrete and get the outcome you want. Timber is another option to use and it's more sustainable so the more of it we can use the better, but that doesn't mean we have to only use timber.

    • @mikeveenhuis9160
      @mikeveenhuis9160 2 ปีที่แล้ว +1

      @@mreagle8770 Yes ofcourse materials change under different circumstances. Timber however is the most severe. Especially considering you can load timber in different directions, longitudinal radial and tangential. Where the latter two are much more susceptible to deformations. Furthermore, timber can draw in moisture, and this also changes the sizes of the elements a lot. This doesn't happen (as much) in steel and concrete. Lastly, creep does happen in all materials, but creep in timber is vastly different than creep in steel or concrete, where it hardly ever is a governing load.
      It is important to see timber as a difficult and unique material, with a lot of unique properties, which a lot of engineers still don't (they consider it similar to steel). Yes you can design for it, but it has to be done with these properties in mind.

    • @billsmith5109
      @billsmith5109 2 ปีที่แล้ว

      Has European CLT walked away from the polyurethane glues yet? This was one of the first changes when full scale fire tests were run in North America when considering CLT for use in structure that required a fire rating. Sometimes a term such as ‘softens with heat rise’ is used. Effectively this means no polyurethanes. See APA 320 PRG 320 2019 and elsewhere.

    Great way to show alternative and effective ways to reduce carbon footprint! Tho another problem by using woods is that often countries have bad forest politics which can results in homogenous forests with lack of diversity which leads to low chances of adapting to climate change and stand against forestfires.
    That’s why politics is so important in the work of reducing the effects of climate change and why we can’t rely on good technology. But those two working together can really make changes!

      Lasting is one thing, the other is that wooden support beams tend to flex as they get old. Basically, your floor will be less and less flat over the years. The same might happen for walls in some cases. In 20-60 years it might start to be noticeable.

      I think it's fascinating because of how we've learned so much. In all our time learning about new materials and techniques to save the earth, we've basically ended up realizing that going back to basics is a pretty good idea and I think it's poetic how we almost came full circle and just went with feeding into the already-existing natural cycles for our latest ideas. We don't really need new things to solve the problem, sometimes it's more like new ways of thinking. Cool, isn't it?

      @@pupip55 fun fact: trees sequester carbon, so if we use them we don't emit excessive carbon dioxide. Plastic production likely does nothing to absorb CO2 emissions so paper can be a good alternative.
      Edit: upon reading a Stanford article on the topic to check, I will admit that paper bags are more costly to the environment to manufacture, but plastics have a limited time left because they are made from fossil fuels. The article itself noted that certain reusable plastic bags are much more effective than the conventional thin ones and are both more durable and take fewer reuses to cancel their carbon footprint. They also ended on this important topic: our habits are most important when it comes to how sustainable we can make things. A change in materials (using durable plastic bags for shopping maybe instead of one-time use bags) can help though.

      @@pupip55 thanks for the interesting fact of the day! I decided to read a little into it, and it's a rather intriguing topic. While trees do emit methane (especially in tropical and wetland areas), they at least absorb CO2 in amounts that can contend with the effects of the potential greenhouse gases they release, and might even absorb some of the methane they release. The overall effect is still noted to be positive, as CO2 is a longer lasting gas than methane, despite methane's much greater potency. If we wanted to control methane emissions, we can study tree emissions for sure, though I believe a more direct action can be taken in the moment by changing agriculture. Cows burp plenty of methane, but studies have shown that a seaweed diet reduced emissions by a massive amount. It's just one way to handle things but it's a start!

Also wood having low thermal properties is actually a bad thing. This makes it more susceptible to temperature changes. Concrete works great as a thermal sink helping buildings to maintain a constant thermal temperature. Another reason to use concrete topped floors.
