  2. Tuned mass damper - Wikipedia

    en.wikipedia.org/wiki/Tuned_mass_damper

    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.

  3. Damp (structural) - Wikipedia

    en.wikipedia.org/wiki/Damp_(structural)

    Structural dampness is the presence of unwanted moisture in the structure of a building, either the result of intrusion from outside or condensation from within the structure. A high proportion of damp problems in buildings are caused by ambient climate dependent factors of condensation and rain penetration. [1]

  4. Vibration isolation - Wikipedia

    en.wikipedia.org/wiki/Vibration_isolation

    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 ...

  5. Damp proofing - Wikipedia

    en.wikipedia.org/wiki/Damp_proofing

    Rising damp is the effect of water rising from the ground into property. [3] The damp proof course may be horizontal or vertical. [4] A DPC layer is usually laid below all masonry walls, regardless if the wall is a load bearing wall or a partition wall. A damp-proof membrane (DPM) is a membrane material applied to prevent moisture transmission.

  6. Shock absorber - Wikipedia

    en.wikipedia.org/wiki/Shock_absorber

    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).

  7. Damping - Wikipedia

    en.wikipedia.org/wiki/Damping

    An example of this concept being applied is the brakes on roller coasters. [16] Magnetorheological Dampers (MR Dampers) use Magnetorheological fluid, which changes viscosity when subjected to a magnetic field. In this case, Magnetorheological damping may be considered an interdisciplinary form of damping with both viscous and magnetic damping ...

  8. Seismic base isolation - Wikipedia

    en.wikipedia.org/wiki/Seismic_base_isolation

    Contrary to popular belief, base isolation does not make a building earthquake proof. Base isolation system consists of isolation units with or without isolation components, where: Isolation units are the basic elements of a base isolation system which are intended to provide the aforementioned decoupling effect to a building or non-building ...

  9. Passive fire protection - Wikipedia

    en.wikipedia.org/wiki/Passive_fire_protection

    Fire compartmentation (barriers designated as occupancy separations are intended to segregate parts of buildings, where different uses are on each side; for instance, apartments on one side and stores on the other side of the occupancy separation). Closures (fire dampers) Sometimes firestops are treated in building codes identically to closures.
