What is Vibration control?
In [[earthquake engineering]], '''vibration control''' is a set of technical means for decreasing [[seismic load]]s and improving [[seismic performance]] of [[building|building structures]].[[File:Machupicchu intihuatana.JPG|thumb|left|Dry-stone walls control of [[Machu Picchu]] Temple of the Sun, [[Peru]]]][[File:Taipei 101 Tuned Mass Damper.png|thumb|Tuned mass damper control in [[Taipei 101]], the world's second tallest [[skyscraper]]]] == Types of vibration control devices == All vibration control devices may be classified as ''passive'', ''active'' <ref>{{Cite web |url=http://physics-animations.com/Physics/English/spri_txt.htm |title=PASSIVE AND ACTIVE VIBRATION ISOLATION SYSTEMS |access-date=2010-03-24 |archive-date=2007-02-04 |archive-url=https://web.archive.org/web/20070204101728/http://physics-animations.com/Physics/English/spri_txt.htm |url-status=dead }}</ref> or ''hybrid''.<ref name=ActiveHybrid>{{cite book|title= Active, Hybrid and Semi-Active Structural Control|author=Chu, S.Y.; Soong, T.T.; Reinhorn, A.M.|date=2005|publisher= John Wiley & Sons |isbn=0470013524}}</ref> The first kind is the simplest one and, therefore, widespread. Passive control devices represent different types of ''[[base isolation|base isolators]]'' and ''[[seismic damper]]s''. ''Base isolators'' restrict penetration of potentially damaging [[earthquake|seismic waves]] into a [[building|building structure]] while ''dampers'' decrease destructive effect of those waves. {{Commons category|Structural control}} ==Other websites== * {{dmoz|Science/Technology/Structural_Engineering/Earthquake_Engineering/Control}} ==References== {{reflist|2}} {{Earthquake engineering}} [[Category:Earthquake engineering]] [[Category:Mechanical vibrations]]
