Location of Taipei 101's largest tuned mass damper. When installed in buildings, dampers are typically huge concrete blocks or steel bodies mounted in skyscrapers or other structures, which move in opposition to the resonance frequency oscillations of the structure by means of springs, fluid, or pendulums.
Some other base isolators are designed to slide, preventing the transfer of energy from the ground to the building. Tuned mass dampers Tuned mass dampers reduce the effects of harmonic vibration in buildings or other structures. A relatively small mass is attached in such a way that it can dampen out a very narrow band of vibration of the ...
A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction).
A damper is a valve or plate that stops or regulates the flow of air inside a duct, chimney, ... in turn controlled by a thermostat or building automation system.
Intumescent dampers swell shut due to intumescence in the event of a fire. Unlike mechanical dampers, it is a physical/chemical reaction that causes closure. Cleaning and an age assessment are periodically performed. The annulus of an intumescent damper is closed eliminating smoke migration. Also, intumescent fire dampers can be qualified to ...
After the seismic waves enter a superstructure, there is a number of ways to control them in order to soothe their damaging effect and improve the building's seismic performance, for instance: to dissipate the wave energy inside a superstructure with properly engineered dampers; to disperse the wave energy between a wider range of frequencies;
