A 7.5 earthquake hit Taiwan yesterday and footage shows the Taipei 101 skyscraper shaking.
The 1,670ft building famously has a 703 ton steel ball hanging between the 88th and 92nd floors, which acts as a “dampener system” to reduce building sway by 30-40% during earthquakes and typhoons.
This video explains how the system acts like a pendulum to prevent structural damage.
The engineering marvel is a passive dampening system, which means it doesn’t require an outside power source but is “powered by natural movement of the building.”
Tips til banker som hever renta: Skyld gjerne på økte innlånskostnader, kredittpåslag, markedstilpasning, eller månefaser – for den saks skyld. Men ikke bruk «solidaritet» som unnskyldning for å øke rentekostnaden for folk.
