uses a fascinating piece of engineering called a tuned mass damper—a giant, 660-ton steel pendulum that plays a crucial role in keeping the building stable against strong winds and earthquakes.

Feel the walls shake this morning in north Georgia? The National Weather Service is now reporting a 4.1-magnitued earthquake hit south of Knoxville, Tenn., near the Tennessee-North Carolina border ...

Prof Au cited the example of the 101-storey Taipei 101 skyscraper in Taiwan, which employs a 660-tonne steel pendulum as a damper, counteracting the building’s sway during earthquakes and strong ...

ABSTRACT: This study investigates the application of time-delay feedback active control to the anti-resonant frequency response in a Pendulum Tuned Mass Damper (PTMD) vibration reduction system. An ...

Friction pendulum bearings are an effective ... from high-tech dampers to base isolators, as a key part of earthquake-resistant design. While energy-dissipation devices are effective in reducing ...

The function of Taipei 101's damper ball, which is the largest in the world, is to offset the building’s movement caused by strong winds or earthquakes. The maximum designed swing of the giant ...

Abstract: The viability of exploiting magneto-rheological (MR) dampers for earthquake protection of structures has been investigated. A MR damper requires low electrical power and is inherently ...
