    World Guide – Tuned Mass Damper of the Shanghai Tower

    World Guide List Item – Investigate the Magnetic Tuned Mass Damper of the Shanghai Tower

    From Gizmodo: https://gizmodo.com/how-a-121-storey-building-uses-a-giant-magnet-to-preven-1692540759

    This is where the ‘tuned mass’ damper system of the 2,073-foot Shanghai Tower comes into play. The physics of the damper work exactly as normal — a 1,000 ton weight hangs from steel cables. But two systems prevent the weight from moving too far or two fast: hydraulic rams, and a ‘tunable’, self-generated magnetic field.

    The iron weight hangs above 10m x 10m copper plate, which is studded with 125 powerful magnets. As the iron swings over the magnets, it induces an electrical current in the copper plate, which in turn is enough to limit the motion of the mass. The beauty is in the simplicity: there’s no outside power source, and it’s a completely self-regulating system. The faster the weight moves, the stronger the magnetic field containing it.

  • A Vertical Forest in Milan is Actually Being Built!

    A Vertical Forest in Milan is Actually Being Built!

    I’ll take three, please. Construction has already started on a pair pf buildings in Milan, Italy that incorporate massive planters on the outside of the building which will give homes to about 900 trees and shrubs. This vertical forrest is supposed to help air quality in Milan.

    Interesting to see such a lofty, concepty project enter the actual building stage. However, I think the real trick will be to actually correctly cultivate the plants when the building is completed. In my experience working with Friend of the Highline on the NYC Highline project, I noticed that the final element that was the hardest to fully realize was getting the mix of plants just right to fulfill the architects vision, and to actually work in a sustainable manner.

  • Lecture: How Spatial Arrangement Creates Movement, and Implications for Consumer Shopping Behavior at Ikea

    Here’s a great talk by Professor Alan Penn of the UCL Bartlett School of Architecture, discussing How Spatial Arrangement Creates Movement, and Implications for Consumer Shopping Behavior at Ikea. It’s long, but a great analysis of the topic, with easy foundations of key concepts explained.

    “Professor Alan Penn describes the way that architects use space to sell you things, showing how space creates patterns of movement, bringing you into contact with goods. In IKEA though, the story gets more interesting, here the designers deliberately set out to confuse you, drawing you into buying things that are not on your shopping list.”
