What scale earthquake can the Yokohama landmark tower witstand?

Answer 1

The 972-foot tall building features a combination of anti-earthquake measures. The entire building sits on rollers, which allow the earth to undulate beneath the structure without shaking it. Additionally, the building has an active mass damper system that prevents the building from swinging by weighing it down. And if that doesn't work, the building is made from flexible materials that bend with the earthquake instead of breaking.

Answer 2

The Yokohama Landmark Tower in Japan is designed to withstand earthquakes up to a magnitude of 9.0 on the Richter scale. It incorporates advanced seismic engineering techniques to ensure its structural integrity during strong tremors.

Answer 3

There's really no answer for that question. It's said to be 'earthquake resistant' by the people who built it, but it's never really been specified to what scale.

Considering it was finished in 1993 though, its guaranteed to have been through many earthquakes already.

I saw a special on it when I was living there, and there are a lot of anti-earthquake measures under the hood. The entire building sits on rollers,so the ground can shake and whatnot without affecting the building (if it's a smaller quake). The building's also made of flexible stuff so it can flex, and it has a mass damper pendulum type system that you should Google. Interesting stuff.

Answer 4

2 systems:

1) center column vibration control, with the core column and surrounding steel frame connected by a flexible oil damper

2) added mass control mechanism aka mass damper, for this tower it's his core column
