TitleTapered Steel Energy Dissipators for Earthquake Resistant Structures
AuthorsTyler, R.G.
PublicationBulletin of the New Zealand National Society for Earthquake Engineering Vol.11, No.4, December 1978.
ObjectivesShow the effectiveness of round and plate tapered-steel cantilevers as energy dissipating devices.
AbstractThe paper desribes the testing and design of tapered-steel cantilevers used as energy dissipating devices, manufactured from either a round bar or plate, which can be used in isolation systems to protect buildings or bridge decks against earthquake attack. The steel cantilever energy absorber is a simple device which can be manufactured from steel supplies normally available in an engineering store using standard engineering practice.
