Looking at the Etihad Stadium, and it's airplane-like features, I was thinking: Imagine a relatively heavy roof, shaped like a sail, connected to its building with a rack and pinion-system. When the wind picks up the roof, the pininons harvest energy. The roof then spills the wind, like a sail, and gravity returns it to its original position. The pinions harvesting energy again. Has something like that ever been tested?

When you put all these different shaped buildings together, you can get some hard to predict behaviour of the wind. This can include wind being directed up or down as well as creating high and low speed and pressure areas around buildings. Trying to predict this with computer simulations is challenging as there is just so much physics going on, so wind tunnel testing is essential. Very interesting stuff.

@hateclub Ай бұрын

A good example of unintended wind effects is the Bridgwater Place building in Leeds, which caused wind to funnel past one specific section of road and ultimately one person died when a lorry blew over. Now they have wind deflectors in place by the road.

@LSmallCatL Ай бұрын

I'd be surprised if anyone in the construction industry wouldn't be familiar with RWDI. There aren't many options for wind tunnel testing around the world considering the required facility and associated costs. Smaller projects often go to Computational Fluid Dynamic software tools which are much cheaper and faster however lack the applied testing which you get from a wind tunnel test. Every project however has to consider wind loads in their structural calculation. One caveat however is to be considered. Different regions/ countries have different standards/ requirements which usually is based on the worst condition experienced since windspeeds were measured. Therefore, higher wind loads due to climate changes will fall into the applied safety factors which have to be rather higher than lower to avoid a sudden collapse of any structural if unprecedented conditions apply.

twin towers were 1st skyscrapers to be tested in a wind tunnel - but - they only tested 1 tower alone (they didn’t test both towers side-by-side); there was also a notoriously harsh wind that went through that plaza between those towers. Also, they built 2 moving rooms that simulated how the wind would be experienced by the occupants when the buildings swayed; For both tests many people found the simulated motion disturbing. The engineers came up with motion dampers to absorb the sway; the 1st time any such dampening device was used in a building. (No conclusive evidence that the dampers worked). Great video - thanks for sharing! 🙂👍🏼👍🏼

I'm currently living in Chicago, where one of the city's newest supertall buildings is the St Regis Chicago. This mixed-use tower was designed by Studio Gang. Late in the construction phase, it was determined that it would be necessary to leave floors 83 and 84 unfinished, creating a blow-through in order to stabilize the top floors above. While this did solve the issue of building sway at the top, reducing it by 20%, it looks like a flaw in the design. I wonder if this advanced wind tunnel modeling could have been used to solve the problem while the architects were still at the design stage. I can think of another example, the Shanghai Financial Centre, designed by Kohn Peterson Fox, which has a hole at the top as part of the overall design.

Welp, after some quick research once I finished the video I’m sad to find out that NJ actually does not fall in the top states for roundabouts 🙈 in fact out of the 110 found on Wikipedia, about ~45 are now defunct smh. But To be fair my hometown of ~2 sq. Miles contains 2 itself plus another ~15 in nearby towns I regularly work in or drive through which is about 25% of them in the state!

This is the kind of content I love on this channel, so interesting to learn what seem like finer points but are major parts to large construction. I recently left a job at the £1.3 billion AstraZeneca Discovery Centre in Cambridge UK and from my short time at that facility, I cannot believe this type of research was employed in it's construction. The wind would funnel and increase in the open spaces surrounding the building. Maybe the long term plan with the new train station would negate this effect, I do not know, that's Fred's job to tell me otherwise. Regardless, for £1.3 billion, it felt like shortcuts had been made.

I wish you would've showed the meaningfulness of the wind-test in action. Show footage from a slo-mo camera deforming the little models while the experts describe that the model is performing within desired tolerances - or not. Even just animated models with data from real life showing little stress points in blue, green, orange and red... That's what I want from this sort of video. And when you talk about scaling, how do they scale accurately, so the model - which is not built of steel and concrete - accurately reflects how a steel and concrete structure will behave? Again, that's the sort of thing I want from a video like this...
